In detail: do-it-yourself repair of a vaz 2106 adjustment from a real master for the site my.housecope.com.
The legendary "six", which was almost the main car in the country, is less and less common on our roads. Now, few people specialize in the repair and maintenance of VAZ classics, and it is rather difficult to find a master for setting up its power system. However, any car owner is able to independently establish a unit for preparing a combustible mixture, it is enough to use the recommendations of experienced drivers.
Before adjusting the carburetor on the VAZ 2106, it does not hurt to find out its design features. After 1980, Ozone and Solex began to be installed on Togliatti cars. The point of operation of the unit is the preparation of a combustible mixture before feeding it into the cylinders of the car. To the subtleties, this is not a driving school, we will not disassemble the structure, it is enough to get acquainted with the main components that ensure the optimal operation of the carburetor ICE:
Fuel dosing system.
Mechanisms for throttle valve control and mixture enrichment.
Idling system.
Accelerator pump and econostat.
Float chamber.
A chamber with a float and a needle valve is responsible for the stability of the fuel level. Further, gasoline, flowing through the spray pipe, enters the chamber, where it mixes with air from the inlet pipe. The amount of the mixture is adjusted by the throttle valve, which is associated with the accelerator pedal.
Fine adjustment allows the correct mixture of gasoline and air to be prepared in a 1:15 ratio. In the process of long-term operation of the machine, the settings go astray and you have to think about how to adjust the carburetor on a VAZ 2106 car on your own. The adjustment technology is the same for both Solex and Ozone.

Setting up the carburetor assembly is no more difficult than adjustment of the clutch drive on the VAZ 2107 since it only involves adjusting the jets. In some cases, they need to be cleaned of resins and other contaminants, the presence of contaminants is felt by power failures during the acceleration process. Many car owners claim that Ozone carburetors are not a good option and recommend replacing them with Solex.
Nevertheless, the signs that the device has begun to prepare a rich mixture, and its adjustment is needed, are the same for both types of units:
Increased fuel consumption.
Frequent overheating of the motor.
Black smoke from the exhaust pipe and pops.
Loss of power.
Lean mixture preparation is characterized by the following features:
Pops in the carburetor.
Loss of power.
Overheating of the engine.
Of course, you don't always need to grab onto the screwdriver and turn the adjusting screws right away - it may be something else. For example, when the idle speed is floating, air may leak through the intake manifold gasket, and there may be a breakdown of the brake booster diaphragm. But even the reasons listed are not all options, so specific recipes for eliminating certain problems cannot be given. The issue should be solved in a complex way, taking into account the connection between the vehicle systems.
A full-fledged setting of the unit for the preparation of a combustible mixture requires a systematic approach. The whole cycle consists of the sequential execution of the following stages:
Preliminary phase.
Float adjustment.
Idle speed adjustment.
Adjustment of the carburetor unit rod ends.
Before, how to properly adjust the carburetor on a VAZ 2106 with your own hands, it is important to perform a number of work activities:
Adjust the thermal clearances of the timing mechanism.
Set the optimum ignition timing.
Open the air damper fully.
All work on setting up the carburetor unit is carried out on a warm engine. Do not forget that during the process you may need new parts and rubber products, so it is better to purchase a repair kit in advance.
One of the main stages in setting up the carburetor unit. A high level will produce a "rich" mixture, and more of it will be supplied to the cylinders, but the expected dynamics will not be there. Only fuel consumption will increase, as well as its toxicity.
The float tongue must be set so that its travel is no more than 8 mm. In some cases, the needle valve may be the cause of the problem. Then you need to remove the float, pull out the needle and check the patency of the holes.
The process involves two screws that set the quantity and quality of the mixture. For a high-quality setting, the presence of a gas analyzer will not interfere. Before adjusting the carburetor on a VAZ 2106 car, you need to know about the restrictive plastic bushings that are pressed onto the adjusting screws. These plugs prevent you from breaking the factory settings. If this factor interferes with setting normally XX, then break them off with a slotted screwdriver.
Idle speed control technology:
With the air damper open, set the crankshaft speed to 800-900 rpm with the quality screw.
Turning the quality screw, set the maximum engine speed.
Set the rotational speed of 950-1030 rpm by the number screw on the tachometer.
Set the maximum speed again with the quality screw.
Repeat these operations until the moment when the speed of 950-1030 rpm does not coincide with the maximum speed set using the quality screw.
After the moment of coincidence, return the quality screw to the position where the engine speed was 800-900 rpm.
In the presence of a gas analyzer, the quality screw achieves a CO concentration in the exhaust gases of 0.5-1.2%. The final position of the screws must be fixed with a plastic sealant to prevent spontaneous loosening.
An equally important stage in the process of adjusting the carburetor of the "six" is carried out according to the transitions:
Dismantle the air filter and its housing.
Measure the distance between the center points of the tips, it should be 80 mm.
To change the length of the rod, release the tip with a screwdriver and unscrew the lock nut with a “8” wrench, and then adjust by rotating the tip.
Tighten the fasteners and install the rod to its original place, start the engine and press the gas pedal all the way. If the throttle does not open completely, then the damper has a power reserve.
When asked how to further adjust the carburetor on a VAZ 2106 car, experts recommend performing a few more simple steps:
Remove the longitudinal type rod end and unscrew the lock nut.
Reduce the length of the rod, fix it and again check the degree of opening of the damper by pressing the gas pedal to the floor. The damper must be absolutely closed.
If you need to increase the length of the link, you must loosen the throttle cable.
Checking the adjustments of the mixture preparation unit is as important a maintenance step as battery condition monitoring car. An integrated approach to setting up the carburetor guarantees not only a comfortable travel mode, but also a lot of useful points:
An increase in power and a steady set of speed.
Absence of failures in the operation of the internal combustion engine in the low and medium speed sector.
Improved dynamic performance - the car picks up speed faster and accelerates in a short time.
Optimum engine response, which translates into responsiveness of the gas pedal.
The listed qualities make it possible to effectively use the combustible mixture, which is necessary both in urban traffic jams and on suburban roads.Therefore, competent adjustment of the carburetor unit will help the car pick up speed in a timely manner and make the planned maneuver.
The carburetor is an integral part that prepares the fuel mixture for the engine. Its task is to ensure the correct mixing ratio of air with gasoline. The ratio is considered ideal: 1 portion of gasoline for 15 portions of air. During operation, the adjustment of the VAZ 2106 carburetor gradually gets lost, which leads to excessive enrichment or depletion of the fuel mixture with gasoline.
If the carburetor starts producing a rich mixture, you will understand this by the following signs:
Fuel consumption increases
Loud exhaust is heard in the muffler and the smoke turns black
If the engine receives a lean mixture, you will understand this by the following sign:
Loud bangs are heard from under the hood.
In both cases, the engine heats up noticeably more, and its power is lost.
If you encounter this problem, remember that it is a natural consequence of using the carburetor. Any element of the car requires care, regular inspection and maintenance. Therefore, from time to time, the VAZ 2106 carburetor should be tuned.
Before proceeding with the adjustment, you need to make sure that the failure of any element inside the device has not become the cause of the breakdown. You need to disassemble it, rinse and clean it. And only after you are convinced of the complete serviceability of all components of the structure, you can start adjusting.
The easiest option is to send the car to a specialist. Carburetors have a special tool available - a gas analyzer. With this device, you can achieve the most efficient system configuration. However, the services of specialists in this profile are not cheap. You may want to do all the work yourself, using the means at hand. Next, we will look at how to set up the carburetor step by step.
Check the length between the tips. The required size is 80 millimeters.
If you deviate from this size, take out one tip.
We loosen its lock nut and, by rotating, adjust the distance to the desired size.
Tighten the nut and return the traction.
You need to check the adjustment. To do this, our assistant squeezes the gas pedal. We observe the throttle valve - whether it has opened completely.
If not, then you need to remove the tip from the lever and reduce the length of the rod.
Now you need to see what position the damper is in when the gas pedal is released: does it close completely. If not, the traction should be lengthened a little.
Next, we work with the air damper. We loosen its drive. We completely recessed the damper in the cabin.
We press on the three-arm lever so that the damper opens to the end. In this position, tighten the locking screw.
Checking the adjustment. To do this, completely close and reopen the shutter from the passenger compartment. If the damper does not open completely, we carry out the adjustment again. If the outcome is positive, fully tighten the screw.
Previously, the VAZ 2106 carburetor must be removed. How to do this is described in the article:
The following step-by-step photo instruction will help you deal directly with the adjustment process:
These works can be done right in the car. But you have to first remove the filter cover.
