Chainsaw poulan 2150 DIY repair

In detail: a chainsaw poled 2150 DIY repair from a real master for the site my.housecope.com.

The chainsaw is a worthy replacement for hand saws and axes. Today, this tool is available in almost every household - it is indispensable for setting up a personal plot, construction and repair work. Intensive use and improper care of the tool can lead to premature failure. However, the owner of the chainsaw does not have to go to the workshop right away - many of the faults that can happen to her during operation are quite realistic to eliminate on their own.

Correct diagnosis is essential for a successful repair. Therefore, in order to determine why the chainsaw failed and, most importantly, how to make it work again, you first need to know the features of its design.

It should be noted that it does not differ in particular complexity, since it includes:

engine (two-stroke gasoline);
functional part (saw bar and chain);
systems that ensure the joint operation of these two units (ignition, filtration, lubrication, etc.), that is, the tool as a whole.

In order to simplify the diagnosis of malfunctions, it is customary to distinguish them into two main categories:

engine malfunctions;
malfunctions of other parts of the chainsaw.

Most often, failures occur in the engine systems, however, the rest of the tool, due to intensive use or improper care, can fail at any time. How to determine exactly where the breakdown occurred? Simple logic will help us with this.

If the problem is in the engine, it will:

do not start;
deafen;
work unstable;
overheat;
smoke;
develop insufficient power.

As for all other malfunctions, as a rule, they manifest themselves with a normally operating motor.

If your chainsaw won't start, the first thing to do is to check for a mixture of fuel in the tank. By the way, it must be prepared in the proportions indicated by the engine manufacturer, otherwise the instrument will simply not start.

After verifying that the fuel mixture is correct and available, the ignition system should be checked. To do this, you need to inspect the spark plug.

Her condition can say a lot:

indicates that the fuel mixture does not enter the carburetor, which means that the problem is not in the ignition;

fuel-splattered candle

is the result of an overabundance of the fuel mixture, which lies either in a violation of the engine starting algorithm or in an incorrect carburetor adjustment;

this is a signal about the presence of low-quality oil in the engine lubrication system, incorrect carburetor settings, or an incorrectly prepared fuel mixture.

If the spark plug is splashed with fuel, wipe it thoroughly after removing it. The fuel supply system should also be cleaned. To do this, it overlaps, after which the starter is turned on. A carbonized candle must be carefully cleaned with an awl and emery.

When checking the spark plugs, you should pay attention to the distance between the electrodes (the normal gap is 0.5-0.65 mm), as well as the condition of the gasket and the presence of a spark. A damaged or worn gasket will have to be replaced, and the spark can be checked by putting on the ignition cable, connecting the cylinder and plug nut, and starting the starter.

If the discharge does not occur, the plug must be replaced. In the event that a spark does not appear with a new candle, then the problem is in the connection to the high-voltage wire or in it itself.

If the fuel mixture does not flow into the cylinder, but the spark plug is working properly, this may mean that:

Clogged fuel filter.

To clean this unit, remove the fuel hose and check the jet. If it is weak, the filter must be removed through the filler hole of the fuel tank and cleaned or replaced if completely worn out.

As a preventive measure, it is recommended to replace the fuel filter at least once every 3 months.

This is nothing more than a hole in the fuel tank cap, which is cleaned out with an awl.

The fuel mixture is not supplied or is supplied insufficiently.

There may be several reasons for this:

the air filter is clogged (in this case, it must be removed, rinsed with water, dried and replaced);
the carburetor settings are out of order (which means this unit needs to be re-adjusted);
the integrity of the carburetor membrane is broken (must be replaced);
the channels of the carburetor are clogged (it must be disassembled and all parts and assemblies must be cleaned).

If at low speeds the engine of the chainsaw works normally, but at high speeds it starts to stall and smoke, the problem may be hidden in the muffler.

To check the quality of its work, you should do:

dismantling (with the obligatory closing of the outlet);
disassembly (if the muffler is collapsible);
cleaning from carbon deposits using special detergents or dry method;
drying (using a hair dryer);
reassembly and assembly.

Dry cleaning without respiratory protection is not recommended. The carcinogens present in the soot will be released into the surrounding atmosphere in the form of dust, the inhalation of which is extremely hazardous to health.

To prevent clogging of the muffler during the operation of the chainsaw, you should carefully monitor the composition of the fuel mixture and the quality of its components.

If the chainsaw engine does not start or cannot develop normal power, it is likely that sufficient pressure does not build up in the engine cylinder for combustion of the fuel mixture. The reason for this may be the wear of the elements of the cylinder-piston group - the piston, rings, bearings, etc. In order to assess the condition of this unit, it should be visually inspected, having previously removed the muffler.

For a more complete diagnosis, a compression gauge is placed in the spark plug hole of the two-stroke engine of the chainsaw. It measures the compression in the engine. Based on the results of the check, one can judge the state of the CPG, however, the exact facts can only be obtained with a complete disassembly of the unit.

If the piston is chipped or scratched, it will obviously need to be replaced. The same applies to deformed or broken piston rings - for normal engine operation, they must be completely intact and free of carbon deposits.

A properly working carburetor guarantees maximum efficiency of the chainsaw, that is, it is possible to develop full power with the most economical consumption of the fuel mixture. The adjustment of this unit is usually carried out by the manufacturer, but its design provides for the possibility of adjustment already during operation.

The fact that such a setting will have to be performed by the owner of the chainsaw is evidenced by:

Strong vibrations or damage to the protective cover.
CPG wear.
Carburetor clogged.
Inability to start the engine or its spontaneous stops after starting.
Increase in fuel consumption and emissions while decreasing engine power.

Chainsaw carburetor adjustment is carried out in strict accordance with the manufacturer's instructions using three special screws, which are responsible for the maximum ("M") and minimum ("L") revolutions, as well as the idle speed of the engine ("T"). In order to exclude unwanted interference by an inexperienced user with the carburetor operation, some manufacturers install only one idle screw.

Carburetor adjustment is carried out in two stages:

Basic (carried out with the engine off).
Finishing (carried out with a running, pre-warmed engine).

For basic adjustment, screw in screws H and L as far as the stop and back out 1.5 turns. Final adjustments require the engine to warm up for 5-10 minutes at low revs.

The final calibration is performed by unscrewing the idle screw until the minimum engine speed is reached (in this case, its operation must be stable, and the chain must be stationary). If the engine stops at idle speed, the screw must be returned back, and if the saw chain is still in motion, continue turning counterclockwise.

Calibration check is performed by test:

Acceleration (with a smooth press on the accelerator, the engine should quickly pick up speed to the maximum indicator).
Maximum speed (if there is an ignition interruption, screw H should be slightly loosened).
Work at idle speed (the chain should not move, and the engine should pick up speed as quickly as possible).

If the owner of the chainsaw is not familiar with the carburetor device and does not have the tool necessary to calibrate it, contact a specialist. The carburetor is a very complex unit, so any wrong action can lead to irreversible consequences, for example, complete engine failure.

If the diagnostics showed that everything is in order with the engine and its systems, then the cause of the malfunction should be looked for in other units of the chainsaw. The most common problems are:

failure of the starter;
improper operation of the lubrication system;
incorrect operation of the chain brake;
saw chain wear, etc.

If the cause of the tool failure is not visible to the naked eye, as is the case with the engine, it is necessary to perform a thorough diagnosis of the faults and eliminate them in accordance with the manufacturer's recommendations and safety regulations.

DIY chainsaw carburetor setting

For an independent carburetor option, it is necessary to familiarize yourself with its device and understand the order of work that is carried out to adjust the parts responsible for the correct functioning of the component parts of the device and parts close to it.

It is necessary to carefully handle the items for the system option, and also to determine whether the set characteristics correspond to very permissible values.

The carburetor serves to mix the combustible consistency with air, observing the proportions established in advance. If clear doses are not followed, the proper functioning of the motor is at risk. When a huge amount of air enters during mixing of a component, and there is not enough fuel, then such a mixture is considered "poor".

Over-saturation should not be allowed, because with a large amount of fuel, in comparison with air, malfunctions or engine wear are also likely. Adjustment of the carburetor is needed not only before the initial introduction, but also when any differences in its operation are revealed. Before using your chainsaw, do not forget to run it in.

Components of the carburetor

The carburetor design contains a standard set of parts, but may vary slightly depending on the manufacturer. Components:

The foundation... It is a special tube that visually resembles an aerodynamic structure. Air passes through it. In the transverse direction in the middle of the pipe there is a damper. Its position can be changed. Chainsaw adjustment poulan 2150 - forum. The more it is pushed into the passage, the less air enters the engine.
Diffuser... This is the constricted part of the tube. With its help, the air flow rate increases exactly in the segment from which the fuel comes out.
Channels for fuel supply.The fuel mixture is contained in the float chamber, then passes into the nozzle, from which it flows into the sprayer.
Float chamber... It is a separate structural element, reminiscent of the shape of a tank. Poulan 2150 chainsaw device; poulan 2150 chainsaw carburetor adjustment; instructions for working with the poulan 2150 saw. Designed to constantly maintain an optimal level of fuel fluid in front of the entrance to the air channel.

Alternatively, research foreign chainsaw manufacturers such as Calm.

Every carburetor owner should have the necessary tools to adjust this system. There are three adjusting screws located on the body of the device. They have their own markings:

L - screw for low speed correction.
H - screw for adjusting high rpm.
T - regulates the idle speed, in most cases it is used for experiments.

Chainsaw air filter

Before adjusting the carburetor, you need to prepare the device:

The engine warms up, that is, it starts about 10 minutes before the repair, and turns off when you start work (see how to start the chainsaw).
The air filter is checked and washed.
The chain is stopped by turning the screw T as far as it will go (see chain oil).

To carry out a safe repair, you need to prepare a flat surface where you can carefully position the device, and turn the chain in the opposite direction. We need a tachometer. It determines the presence of a malfunction in the carburetor. When the screws are turning, the sound should be perfect and absolutely smooth. If you notice squealing notes, then the mixture is oversaturated.

Carburetor adjustment is divided into two main steps. The first is called basic. It is performed with the engine running. The second is performed when the engine is warm.

To carry out the carburetor tuning procedure successfully, you need to read the operating instructions in advance specific model to identify additional features of the device configuration.

The adjusting screws of the highest and lowest speed should be moved clockwise until the highest resistance is encountered. When the screws reach the stop, you need to move them in the opposite direction and leave them after 1.5 turns.

The engine turns on at medium speed and warms up like this for about 10 minutes. The idle speed screw must move clockwise. Another adjustment of the saw https: reanimation of the chainsaw pole 2150 2005 pole 2150. It is released only when the engine comes into stable operation. It is necessary to check that the chain does not move during this process.

Chainsaw Poulan/ Partner carburetor repair,adjustment carburetor.In idle mode, the engine may stall (the reason is here). In this case, immediately turn the adjusting screw clockwise until it stops. Sometimes the chain starts to move. In this case, turn the adjusting screw in the opposite direction.A little research needs to be done. Device acceleration is initiated. The serviceability of the engine should be assessed during the maximum revolutions. Poulan chainsaws. Carburetor adjustment. Poulan 2150. Chainsaw poled 2150. When the engine is functioning properly, it means when the accelerator is pressed, the speed rises rapidly to 15,000 rpm. If this does not happen or the increase in speed is too slow, it is necessary to use the screw marked with the letter L. It turns counterclockwise.Moderate movements must be observed, since the turn cannot be more than 1/8 of a full circle.To limit this value, you need to use the screw marked H. To increase the number of revolutions, turn it clockwise, and to decrease them in the opposite direction. The maximum frequency should not exceed 15000 rpm. If you increase this indicator, the engine of the device will work for wear, which will lead to problems in the ignition system. When turning this screw, the ignition processes of the device must be taken into account. Advantages, disadvantages, price, technical characteristics, analogs, adjustment and reviews of the owners of the poulan 2150 chainsaw. If the slightest glitches appear, then the maximum value of the revolutions must be reduced.Before this procedure, it is necessary to perform a full adjustment of the components of the carburetor when operating at maximum speed. Next, you should check the functioning of the device in idle cold mode. When the correct parameters are achieved during the adjustment, you can see the exact conformity of the carburetor design to the following criteria:

When the idle cold mode is connected, the chain does not move.

Chainsaw accelerator

When the accelerator is pressed even slightly, the engine picks up speed at an accelerated pace. With a gradual deepening of the pressure, you will notice that the engine speed increases commensurately, reaching the maximum allowable values.
When the engine is running, you can compare its sound to a four-stroke instrument.

If violations are noticed in the above parameters or the device was not completely adjusted, you need to perform the main setup step again. Chainsaw repair poulan chainsaw diagnostics and adjustment, poulan p 2150. Sometimes actions are performed incorrectly. In this case, the device may fail due to the loss of the correct node settings. In this case, you will have to contact a specialist.

The device of different models of carburetors is almost the same, so when working with them, you can use the standard scheme. All elements must be removed carefully, and then lay out in the order belowso that you can successfully place the items in place after the completion of the repair work.

Removing the top cover

The top cover is removed. To do this, unscrew the 3 bolts holding it in a circle.
The foam is also removable, as it is the upper part of the air-conducting filter.
The fuel hose is removed.
The drive thrust is output directly to it.
The cable end is disconnected.
The petrol hose can be completely removed by pulling it off the fitting in a systematic way.

To finally prepare the carburetor for overhaul or replacement of the smallest parts, you need to carefully disconnect it from the main system... Sometimes further disassembly is required. Unscrew the components carefully and stack the fasteners in groups, as these small parts are easily lost.

In order to properly configure the carburetor of a Chinese chainsaw, you must first remember the factory settings of the device, then turn on the engine. Subsequently, you will have to leave it to work for several hours in order to accurately set your own parameters. Sometimes work is performed once after ten minutes of engine operation, but many Chinese-made models require special handling.

Chinese Chainsaw Model

Adjustment procedure:

Activities start in idle mode... With the help of the adjusting screws, you need to achieve a systematic set of revolutions by the engine, so you should first let it run at low speeds. The deviation from the norm is the movement of the chain along the tire. In this case, you need to adjust the extreme screws to the optimal position so that the chain remains stationary.
Transition to medium speed rpm is in progress... Sometimes the engine will smoke. This defect can be eliminated by tightening the screw for supplying a leaner fuel mixture.

In this case, the smoke will disappear, but the engine speed will increase. It is necessary to adjust the settings until the level is reached when, when pressing the throttle, the engine smoothly picks up speed, no sudden jerks or interruptions are heard.

The device motor is being checked... The device of the poulan 2250 chainsaw. Adjusting the carburetor of the poulan 2250 chainsaw. The poulan 2150 chainsaw. The chainsaw is transferred to minimum speed, and then the lever is pressed rapidly. At maximum pressure, it is held for 3 seconds. If there is an abnormality in the operation of the engine, gradually loosen the screw until the optimum position is reached.

The chainsaw should run for several hours under real conditions.... It is necessary to engage in sawing wood, and then inspect all the elements involved in this event. If there are deviations, they must be corrected using adjusting devices. When all defects have been eliminated and optimal settings have been established for supplying a properly concentrated fuel, the process of setting up the device can be considered complete.

Look clearly at the video:

In order for the chainsaw to work properly, you need to carefully perform work on adjusting the carburetor in exact accordance with their sequence. If there are any irregularities in the operation of the device, it is necessary to completely disassemble it yourself. In most cases, it is necessary to replace any parts that have become unusable.

With a constant check of the quality of the carburetor settings and the implementation of timely actions to improve its operation, problems with the chainsaw do not arise.
