Vaz 2101 do it yourself carburetor repair

In detail: vaz 2101 do-it-yourself carburetor repair from a real master for the site my.housecope.com.

Adjusting the VAZ 2101 carburetor is a very important procedure, without which any car cannot function normally, and even more so, such an age one as a "penny". It is important to note that carburetor adjustments have been taught for more than one year, and there is even such a profession - a carburetor, but we are firmly convinced that with a certain package of knowledge and without fear of "getting your hands dirty", absolutely every car owner can handle it. It is for this reason that we decided to compile a sufficiently detailed instruction for you so that you can save your money and continue to enjoy trips on real domestic classics.
If you are tired of adjusting and repairing the carburetor, as well as the solid fuel consumption of your penny, you should pay attention to the eleventh generation Corolla cars at toyota-ua.com/models/new-corolla. The 2013 Toyota Corolla delivers significant fuel economy thanks to an injector that provides consistent, efficient engine operation and less polluting emissions.

Correct the throttle position

The first step in adjusting the carburetor on a "penny" is to set the correct throttle position. To do this work correctly, you must perform the following simple manipulations:

Step 1: in manual mode, rotate the throttle control lever counterclockwise to fully open.

Step 2: measure the distance to the primary camera, it should be in the range from 12.5 to 13.5 millimeters. If it is not, correct it by bending the tendril of the traction.

Step 3: measure the value of the maximum opening of the throttle valve, it should be in the range from 14.5 to 15.5 millimeters. If this is not the case, then you should correct it by tightening the pneumatic actuator stem.

Correcting the starting device

At the second stage, adjusting the VAZ 2101 carburetor consists in setting up the starting device. As in the previous case, we will provide step-by-step instructions that will help you easily and simply cope with the task.

Step 1: in manual mode, rotate the secondary throttle lever counterclockwise to close.

Step 2: check that the tip of the traction arm is firmly attached to the primary throttle shaft and is located at the very end of the trigger stem. If you find that this is not the case, then you will need to correct its position by bending the rod.

Important! You need to bend the rod very carefully, since too much pressure can break it off.

Adjusting the performance of the pump accelerator

The third stage of adjusting the operation of the carburetor on the VAZ 2101 is to control and debug the pump accelerator.

You need to start working with it with a performance check. To do this, you must collect the fuel in a beaker, which is depleted in 10 full cycles of the throttle control lever. You you should get from 5.25 to 8.75 cubic centimeters of fuel... If this is not the case, then you will need to carry out a full pumping of the pump 9-10 times, and then re-measure. If this does not help, then you will have to completely change the accelerator of the fuel pump.

We set the correct idle speed of the car engine

Adjusting the VAZ 2101 carburetor at the final stage consists in setting the correct engine idle speed. To do this, you must follow these simple steps.

Step 1: warm up the engine for 10-15 minutes.

Step 2: Stop the engine and close the quality screw and the quantity screw as far as it will go.

Step 3: loosen the quantity screw 3 turns and the quality screw 5 turns.

Step 4: start the engine and set the engine speed to 800 rpm with the number screw.

Step 5: start to tighten the quality screw slowly, thereby reducing the enrichment of the fuel mixture. This should be done until the turnover starts to fall.

Step 6: Unscrew the quality screw half a turn and fix.

As you can see, adjusting the carburetor is as easy as adjusting the VAZ 2101 valves. The main thing is care and accuracy, and you can easily cope with the task yourself.

From time to time, the owners of carburetor Zhiguli are puzzled by uneven engine idling, failures during acceleration and poor starting. One of the reasons for these problems is a malfunction of the fuel system, in particular the carburetor.

A large number of classic Zhiguli models use a VAZ 2101 carburetor in various modifications. There are several modifications of the produced carburetors, which differ not only in the size of the installed jets, but also in the presence or absence of a vacuum corrector system.

The VAZ 2101 carburetor of all modifications is intended only for the VAZ 2101 and 21011 engines, where the ignition distributor is installed without a vacuum corrector. On cars of a later release, systems are installed that are already equipped with vacuum correctors. It should be remembered that the use of carburetors going to VAZ 2101, 21011 and 2105 engines without a vacuum regulator cannot be used on other engines and vice versa. The carburetor VAZ 2103 and VAZ 2016 are similarly used - only on models where there is no vacuum corrector.

Maintenance, adjusting carburetors at home is a rather complicated procedure that requires certain skills, knowledge and tools. You can independently adjust the idle speed, replace the gaskets, clean the jets, fuel channels, and visually check the operation of the accelerating pump, replace it if necessary. But it is advisable to carry out the final revision with adjustment in a car service that has diagnostic equipment to check the level of carbon monoxide in the exhaust gases.

The device of carburetors is fundamentally little different and consists of the following systems:

Fuel level maintenance and regulation system;
Engine start and warm-up system;
Idling system;
Accelerator pump;
Main dosing system;
Econostat systems.

The float in the carburetor's float chamber is responsible for the fuel level. Both excessive and insufficient fuel levels will negatively affect engine performance. This malfunction occurs mainly due to the leakage of the fuel valve, which occurs quite often due to the poor quality of fuel with fuel filters. Cleaning the valve or replacing it in the absence of tightness is carried out after visual inspection, which is a fairly simple operation.

Second-hand carburetor for VAZ 2101

The starting and idling systems are the most vulnerable mechanisms. Poor engine starting is often caused by an incomplete choke. It is eliminated by cleaning with lubrication of its drive. In addition, it is necessary to check how it opens slightly at the moment of starting, which provides the mechanism of the starting device.

If the idle speed is unstable, it is first necessary to check the electric idle valve by applying voltage to it. The absence of clicks will immediately indicate its defect, which will require replacement of the assembly. It is also possible that dirt gets into its channel. It is imperative to clean the nozzle of the valve, then clean the channel.

The idle speed is adjusted as follows.First, you need to achieve the required engine speed with a screw of the amount of fuel mixture (for VAZ engines, this figure is 850 rpm). Then, with the quality screw, it is necessary to find such a position in which the engine will develop the highest speed. If its revolutions are more than 850 rpm, then it is necessary to reduce them with the number screw, and then achieve maximum revolutions using the quality screw. After the rpm is set at 850 rpm, it is necessary to tighten the quality screw until the engine starts to shake slightly. Then unscrew the quality screw back about a third or a quarter of a turn, achieving the most stable motor operation at the leanest mixture.

Another common problem is a malfunction of the accelerator pump, which is manifested by dullness or jerking during acceleration. The defect is checked visually. It is necessary to sharply open the throttle valve, checking the presence and strength of the gasoline jet, which should be uniform for 3-4 seconds. If this is not the case, then it is necessary to check the sinking of the valve or clean the jet.

Perhaps these are the most common simple malfunctions and methods for their elimination. If you cannot resolve them on your own, then it is recommended to contact a professional service.

Owners of the VAZ 2101 model often notice carburetor malfunctions. This leads to increased fuel consumption, unstable engine operation and other troubles. Carburetor repair and adjustment is a simple matter, you can do it yourself without the help of specialists.

It is fairly easy to understand that the carburetor is set incorrectly. This does not require special diagnostics, the main signs of poor performance are the following:

The engine stalls at idle speed.
Clogged spark plugs, making it difficult to start the engine.
Increased fuel consumption and gasoline leakage.

It is worth noting that the above malfunctions are not always associated with the carburetor. For example, unstable operation of the power unit may be associated with a breakdown of the connecting wire that goes to the accelerator pedal. Therefore, before starting the adjustment, you need to make sure that other components and mechanisms are working properly.

As a rule, carburetor adjustment is required after 7,500-8,000 km. If the car is little used, then this work should be carried out at least once a year. Before tuning, clean the candles, distributor well and check the wiring.

Tip: During repairs, new cuffs and jets may be needed, these parts should be purchased in advance.

Adjustment does not require much physical strength, the main thing is to do everything accurately and accurately. We prepare the tool:

set of wrenches;
flat and Phillips screwdrivers;
rags;
latex gloves;
toothpicks;
solvent;
pump or can of compressed air.

The first step is to remove the top cover, float and vacuum valve from the carburetor.

Unscrewing 4 nuts, remove the top cover of the carburetor and clean the chambers

The inner chambers must be well cleaned of dust and soot residues. We clean the small holes with air using a can or a regular pump. We warm up the engine and put it on the handbrake.

Screw 1 adjusts the amount of gasoline supplied, screw 2 adjusts the position of the throttle valve

Advice: The engine idling should be smooth and stable, do not tighten the quality screw tightly, as with a sharp fuel supply, the engine will simply stall.

After finishing the adjustment, it is necessary to make sure that the carburetor is working optimally. To do this, press the accelerator pedal sharply several times. If the engine picks up speed smoothly and does not stall, then the screws are adjusted correctly. Inexperienced car enthusiasts often open the throttle too much, resulting in excessive fuel consumption.Therefore, the number screw must be in such a position that the volume of fuel is sufficient for stable engine idling.It is worth noting that Weber carburetors, which were previously equipped with “pennies”, are not so easy to adjust. Therefore, with a little experience, it is recommended to contact an experienced specialist, since not even all car services know how to properly configure such "rarities".Adjusting the carburetor on a VAZ 2101 will not cause difficulties for experienced car owners. It is better for beginners to do this work with a familiar wizard, since it is difficult to set up the screws correctly the first time. Performing such repairs carefully and according to the instructions, you will make the engine smooth and reliable. Image - Vaz 2101 do-it-yourself carburetor repair

The normal operation of the engine depends on how well the fuel supply to the cylinders is adjusted. Not every motorist can make the correct carburetor settings. Since not everyone is well versed in the power supply system of a carburetor engine.

Maybe it's time to change to a new car? Find out the prices for Hover and be pleasantly surprised!

But if you have at least a superficial knowledge, then it will be easy to make a rough adjustment. It is better to entrust finer adjustments to professionals who ate the dog in this business.

A good way out of this situation is an independent study of all the intricacies of setting up carburetors. This is relevant for cases when there is no competent master nearby. You will need to understand the principles of operation of the VAZ 2101 carburetor in order to know the purpose of all jets in the fuel supply system, since the quality of mixture formation directly depends on them.

Setting up the VAZ 2101 carburetor is necessary for your engine to function normally. How the internal combustion engine works depends not only on its power, efficiency, gasoline consumption, but also, most importantly, on its resource. The good news is that the carburetor does not need frequent adjustments.

Clean all channels, flush it, install new nozzles, and then you just need to change the fuel and air filters in time to ensure the most correct operation of the carburetor. Unfortunately, spare parts on the market are not always of good quality. Therefore, from time to time, there may be some malfunctions in the fuel injection system.

And now it is worth considering what problems can occur in the carburetor. If suddenly the engine starts to work unstable in idle mode, changes in the crankshaft speed are observed, or the engine stalls, if you do not press the accelerator pedal, you do not need to blame the carburetor for the troubles. In particular, this is true for those cases when such symptoms began to manifest themselves sharply, there were no prerequisites for this.

If the carburetor suddenly fails, or some of its units, or its settings go astray, then the change in work does not occur abruptly, but smoothly. Very often, the floating idle speed is caused by the solenoid valve, which is installed on the VAZ carburetor. If your car has a similar device in its design, then first of all you need to check it.

To do this, disconnect the wire that goes to it, and then apply a plus to the valve contact from the battery. If the winding is OK, a small click will be heard. After that, the presence of voltage on the wire, which is connected to the solenoid valve, is checked. If there is no voltage, then there is a destruction of the wiring from the ignition switch to the solenoid valve.

Also, the symptoms described above can appear in cases where there is a very large carbon deposit on the spark plug electrodes. As a result, the spark power is simply not enough to ignite the air-fuel mixture. If carbon deposits are present on the electrodes, then the carburetor itself must be blamed for this. The fact is that it supplies a lot of the air-fuel mixture to the combustion chambers.The saddest reason for this is the burned out intake valve.

But do not grab your head right away, first try to set the gasoline level in the VAZ 2101 carburetor. It is necessary to correctly adjust the position of the float. Often, a penny begins to stall and sneeze at high crankshaft speeds. The carburetor, as a rule, has nothing to do with it. The reason lies in the supply of gasoline. The diaphragm of the fuel pump could already be worn out, but most often the fuel pump rod is erased. You can read about it in a separate article.

Before you start adjusting the penny carburetor, you need to make sure that all components that affect the normal functioning of the internal combustion engine are in good condition. Check spark plugs, electrode gap, distributor, coil, high voltage wires. It is possible to adjust the carburetor on a VAZ 2101 car only at the engine operating temperature (85..90 degrees).

But before starting the adjustments, be sure to purchase a repair kit for the VAZ 2101. And pay attention to the fact that this repair kit matches your carburetor. If Solex is installed, then there is no need to buy a repair kit for DAAZ. Of course, the price of this set is not very high, but if you get the wrong one, you will have to run a little, exchanging for the right one. Disconnect the cable that connects the accelerator pedal to the throttle actuator. The branch pipe connecting the air filter housing to the breather must also be disconnected.

Make sure that there is no vacuum in the hose connecting the carburetor to the advance angle adjuster on the distributor. Now you need to adjust the quality of the mixture. Tighten the screws one by one until the engine starts to shake slightly. Now you need to achieve normal and maximum stable performance. To do this, unscrew the quality screws in turn. Do not make more than one turn. This setting is purely by ear, but it is quite possible to adjust the carburetor of a penny in this way.

Open the throttle and close immediately to determine how well the tuning is done. If the speed rises sharply, there are no delays, then the carburetor is adjusted correctly. But the further operation of the VAZ 2101 car will show more accurately. Carefully monitor how much gasoline is consumed per hundred kilometers. From time to time, check the condition of the spark plugs, if they have carbon deposits, adjust the air supply to the carburetor of the VAZ 2101 car.

The carburetor on a VAZ 2101 car requires periodic tuning and adjustment. Otherwise, the engine will not idle stably during acceleration. It may also be difficult to start. Setting up the carburetor requires some knowledge. However, knowing the technology, how the carburetor of the VAZ 2101 is adjusted, or as it is called in the common people "Kopeyka", you can do the whole procedure with your own hands.

The carburetor device on a VAZ-2101 car is quite simple. It may differ slightly depending on the car model. It's easy to understand that it's time to set up this node. The main features are the following facts:

The engine stalls at idle.
The spark plugs are flooded or carbon deposits have formed, which prevents an easy start of the engine.
Increased or leaking fuel consumption (see fuel consumption table for carbureted vehicles).

In this case, a thorough check of the entire system will be required. In some cases, the above malfunctions are associated with other failures in components and mechanisms.

It is recommended to tune the carburetor before the first signs of malfunction appear. The device of this unit requires adjustment every 8 thousand kilometers. This procedure should be carried out at least once a year, even if the vehicle is rarely used.

Before starting work, if necessary, repair the wiring, distributor and clean the spark plugs. There is a simple technology on how to properly adjust the carburetor on a VAZ 2101.

Jets for carburetors of cars VAZ 2101, VAZ 2103, VAZ 2106, VAZ 2107

During the production of the VAZ 2101, several modifications of carburetors were installed in its system. They differ in the size of the nozzles, as well as the presence or absence of a vacuum corrector. In early Zhiguli models, a carburetor was installed with an ignition system without a vacuum corrector.

The most common carburetor on a VAZ 2101 car is the DAAZ 2101-1107010 carburetor model. A vacuum corrector system is already used here. All carburetor modifications can be adjusted in a similar way. But it is impossible to install a model with a vacuum corrector instead of a design without it, or vice versa. Carburetors of well-known brands DAAZ / Weber, Ozone, Solex are also often used from non-standard carburetors, I would like to highlight Solex 21073 and Solex 21083.

Calibration data for carburetors DAAZ 2101-1107010-01, 2101-1107010-03, 2105-1107010-20, 2105-1107010 10:

If one of the system elements fails in the carburetor, you may not notice this immediately. Failures appear gradually. Often, the instability of idle speed is due to a failed solenoid valve. Not all carburettors have this arrangement.

To test the solenoid valve, you will need to disconnect the wire connected to it. A positive contact is connected to it from the battery. Good wiring is indicated by a slight click.You need to check the voltage on the wire that connects to the solenoid valve. If there is no voltage in the line, the wiring is out of order. It will be necessary to completely replace the network from the ignition switch to the solenoid valve.Unstable rpm can also be observed when the spark plug electrodes are covered with a large layer of soot. The spark power is insufficient. It cannot ignite the fuel mixture. The poor condition of the candles is due to an incorrect carburetor setting. In this case, it feeds too much fuel into the combustion chamber.A burnt inlet valve may be the cause of this malfunction. He is responsible for the amount of fuel that is supplied to the engine combustion chamber. To verify this, you need to adjust the carburetor. If this does not help, you will need to replace the inlet valve.First, you need to prepare the corresponding repair kit for the VAZ 2101 carburetor. You will also need new cuffs, carburetor jets and other spare parts. To adjust the carburetor, you need a repair kit, which includes the following tools:

Spanners.

Rags.

Screwdrivers (Phillips, flat).

Protective gloves.

Solvent.

Toothpicks.

Compressed air canister or pump.

After the appropriate preparation of the repair kit, you can start setting up the VAZ-2101 carburetor. This does not require much effort. All actions must be accurate and accurate.You also need to inspect the nodes on which the operation of the motor may depend. The spark plugs need to be inspected. By their appearance, you can tell in what proportions the fuel is mixed with air.The carburetor must be cleaned. To do this, dismantle its top cover. Removable float, vacuum valve. The interior of the chambers must be cleaned. Soot and dirt accumulate here. Cleaning is carried out using an air canister or using a pump.Another mandatory action is to check the gap between the electrodes of the distributor, as well as the coil and high-voltage wires. Adjustment is carried out only after the motor has warmed up to 90 ° C. The cars are put on the handbrake.Adjusting the VAZ-2101 carburetor begins with adjusting the throttle valve. This is a simple procedure. It can be done in three stages.Manually turn the damper control lever counterclockwise. It opens completely. Image - Vaz 2101 do-it-yourself carburetor repair

The distance to the primary camera is measured. The carburetor design suggests that this figure is 12.5-13.5 mm. If the result is different, you need to bend the tendrils of the traction. Throttle adjustment involves determining the amount of throttle opening. It should be 14.5-15.5 mm. Otherwise, it will be necessary to tighten the pneumatic actuator rod.

At the second stage, it will be necessary to correct the operation of the starting device. Manually rotate the throttle lever on the secondary chamber counterclockwise. It will close. The tip of the link arm should fit snugly against the primary chamber throttle valve shaft.

At the very end there should be a starter rod. Otherwise, you will need to correct its position. For this, the traction is bent. This device is fragile in carburetor engines. If you apply a lot of force to it, the thrust will break off.

You need to start checking with testing the system performance. It is necessary to collect the fuel in a beaker, which is developed in 10 cycles of the throttle lever. Must collect from 5.2 to 8.7 cm³ of fuel. If this is not the case, you need to clean the jets of the VAZ 2101 carburetor. To do this, bleed the pump. This will help clear clogged nozzles. This procedure is performed about 10 times. Then the fuel is measured again.

If the purge procedure does not give the desired result, the accelerator will need to be completely replaced.

If the motor malfunctions at high speeds, you need to check the pump diaphragm. She could wear out. The fuel pump rod is often erased.

Adjusting the fuel system assumes at the final stage adjusting the idle speed. You will need to warm up the engine for 15 minutes. Then the engine must be turned off. The screws of quantity and quality are tightened up to the stop. The first of them must be released 3 turns. The quality screw is unscrewed by 5 turns.

The motor starts. Using the number screw, the frequency of revolutions is set, which is about 800 per minute. Then the quality screw is slowly tightened. This will reduce the enrichment of the fuel mixture. This procedure is carried out until the revolutions begin to fall. After that, the quality screw must be unscrewed another half turn and fixed in this position.

Knowing how the procedure for adjusting the carburetor is carried out, you can do the job well yourself. The engine will run stably, and the VAZ 2101 will operate normally.

VAZ-2101 "Zhiguli" is a passenger car that was born in the Soviet years and has gained great popularity. Many people are still faithful to this model. First, let's figure out what a carburetor is. The carburetor is a kind of mechanism located on internal combustion engines and feeds it with air and gasoline. With its help, these components are mixed. But, as you know, progress does not stand still, and new devices were invented to replace the carburetor - injectors.

This invention was well established, and, since the 80s, it is used to this day. On your Zhiguli you can find various types of carburetors, especially if we are talking about the old Kopeyka. In general, they do not have clear differences. For example, the first two presented models have a valve unbalancing a float chamber. The Ozone carburetor dates back to 1980, its model is 210-1107010-20. You are probably interested in how it is unusual to differ from its relatives mentioned above.

a tube for taking off the vacuum appeared to the vacuum ignition distribution regulator;
a pneumatic drive for the secondary chamber throttle was added;
the diameter of the jets has changed.

The idle system in the carburetor is the most unstable. Therefore, it needs to be adjusted from time to time.The idle speed adjustment elements are 2 screws, one of which determines the composition of the mixture, and the second regulates its amount.

The stroke adjustment must be carried out on a previously warmed up engine and with adjusted clearances, which are located in the gas distribution mechanism. You should also check the correctness of the ignition timing.

Using screw 1, it is necessary to set the crankshaft rotation frequency 820-900 min -1 according to the tachometer of the stand.
Using screw 2, it is necessary to achieve the concentration of CO in the exhaust gases without going beyond 0.5-1.2%.
Using screw 1, restore the shaft speed to 820-900 min -1.
Using screw 2, you need to restore the CO concentration to 0.5-1.2%.
To finish, press the stop marks (plastic bushings) onto these screws, align the splines of these bushings with the locating lugs.

Problems that may arise when setting idle:

There is no engine response to screw tightening (during tightening, the engine should gradually slow down and finally stall). This sometimes happens if there is an excess of gasoline in the idle indicator. The reasons can be:
- very large jet XX;
- the solenoid valve or plug is poorly tightened;
- the XX nozzle seat has a deformation of its structure or the jet is damaged directly.

The ways out of the situation are presented below. So, on the engine running without interruptions at XX, remove the wire from the solenoid valve. Performing this action will cause the engine to stall immediately. If this is the case, then the XX jet is most likely too big and not suitable for you. The solution here is very easy - to purchase and install a smaller one.

If the engine continues to run, then, most likely, gasoline does not enter the XX jet, but goes by. It is necessary to carry out the following manipulations, namely, unscrew the plug (solenoid valve) and conduct a study of your XX jet, whether it is damaged. If deformations are detected, there is no other way but to buy a new carburetor cover. If no deformations were found during your examination, put the nozzle on the valve, lubricate the O-ring with oil and tighten it with a wrench (clamp without using special force, it is advisable to clamp with a wrench using only one finger).

Good engine performance directly depends on how well it is adjusted. Without these steps, you will not be able to enjoy driving your car without interruptions and surprises. So, carburetor tuning must be done for your engine to function properly. Not only the speed and power of your favorite car directly depends on the operation of the engine, but also, which is important these days, the consumption of gasoline!

If the setting is done incorrectly, or you did not consider it necessary to carry out these manipulations at all, then you will have to overpay for fuel consumption. The good news, however, is that you often don't need to tune your carburetor. This procedure should be carried out rarely, the main thing is correct! First, clean its channels, wash your carburetor (it also loves to be clean), install new jets on it. Everything! Three little steps and your carb is happy. And you just need to change the air and fuel filters from time to time.

The only drawback is the quality of the parts that you buy from the market, because you may come across poor quality parts. This can lead to interruptions in the fuel injection system. Therefore, remember the saying "greedy pays twice", and if you have the opportunity to purchase quality parts, be sure to do it! Make your car happy and save your nerves.
