Poulan chainsaw 2150 do-it-yourself repair

In detail: chainsaw poulan 2150 do-it-yourself repair from a real master for the site my.housecope.com.

A chainsaw is a worthy replacement for hand saws and axes. Today, this tool is available in almost every household - it is indispensable for arranging a personal plot, construction and repair work. Intensive use and improper care of the tool can lead to premature tool failure. However, it is not at all necessary for the owner of a chainsaw to immediately contact the workshop - many of the malfunctions that can happen to it during operation can be eliminated on their own.

The main condition for a successful repair is the correct diagnosis. 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 components (ignition, filtration, lubrication, etc.), that is, the tool as a whole.

In order to simplify the diagnosis of faults, they are usually divided into two main categories:

engine malfunctions;
malfunctions of other components of the chainsaw.

Most often, failures occur in engine systems, however, other parts 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;
go deaf;
unsteady work;
overheat;
smoke;
develop insufficient power.

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

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

After making sure that the fuel mixture is correct and available, the ignition system should be checked. To do this, 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 excess of the fuel mixture, which lies either in a violation of the engine start algorithm, or in improper 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 carbon-covered candle must be carefully cleaned with an awl and emery.

When checking candles, attention should be paid 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 spark plug nut, and cranking the starter.

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

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

The fuel filter is clogged.

To clean this assembly, 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 in case of complete wear.

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 with an awl.

The fuel mixture is not supplied or supplied in insufficient quantity.

There may be several reasons for this:

the air filter is clogged (in this case, it must be removed, rinsed with water, dried and put back in place);
the carburetor settings have gone astray (which means this assembly must be re-adjusted);
the integrity of the carburetor membrane is broken (it must be replaced);
the carburetor channels are clogged (it must be disassembled and cleaned of all parts and assemblies).

If the chainsaw motor works fine at low speeds, but starts to stall and smoke at high speeds, the problem may be hiding in the muffler.

To check the quality of its work, do the following:

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

Dry cleaning without respiratory protection is not recommended. The carcinogens present in soot will be released into the surrounding atmosphere in the form of dust, the inhalation of which is extremely dangerous 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 there is not enough pressure in the engine cylinder to burn the fuel mixture. The reason for this may be the wear of the elements of the cylinder-piston group - piston, rings, bearings, etc. In order to assess the condition of this assembly, it is necessary to conduct a visual inspection of it, after removing the muffler.

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

If there are chips or scratches on the piston, it is obvious that it will have to be replaced. The same applies to deformed or broken piston rings - for normal engine operation, they must be fully functional and clean from 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, however, its design provides for the possibility of adjustment 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 cap.
Depreciation of the CPG.
Clogged carburetor.
Inability to start the engine or its spontaneous stops after starting.
Increased fuel consumption and emissions while reducing engine power.

The chainsaw carburetor is adjusted in strict accordance with the manufacturer's instructions using three special screws that are responsible for the maximum ("M") and minimum ("L") revolutions, as well as idling the engine ("T"). In order to exclude unwanted interference by an inexperienced user in the operation of the carburetor, 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, preheated engine).

For basic adjustment, turn the screws H and L to the stop and back out 1.5 turns. Finishing adjustment requires that the engine be warmed up for 5-10 minutes at low speeds.

The final calibration is carried out by turning the idle screw until the minimum engine speed is reached (its operation must be stable and the chain must be stationary). If the engine stops idling, the screw must be turned back, and if the saw chain is still driven, continue to turn it counterclockwise.

Calibration check is done by test:

Acceleration (when you gently press the accelerator, the engine should quickly gain momentum to the maximum rate).
Maximum speed (if there is a misfire, screw H should be slightly loosened).
Idle operation (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, you should contact a specialist. The carburetor is a very complex unit, so any wrong action can lead to irreversible consequences, such as complete failure of the engine.

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

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

If the cause of tool failure is not visible to the naked eye, as is the case with an engine, a thorough fault diagnosis must be made and corrected in accordance with the manufacturer's recommendations and safety regulations.

Setting up a chainsaw carburetor with your own hands

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

It is necessary to carefully handle the items for the system option, and also determine the compliance of the set characteristics with very acceptable values.

The carburetor serves to mix the combustible mixture with air, subject to predetermined proportions. If clear doses are not observed, the correct operation of the motor is at risk. When a huge amount of air enters during mixing, and there is not enough fuel, then such a mixture is considered "poor".

Oversaturation should not be allowed, because with a large amount of fuel compared to air, malfunctions or engine wear are also likely. Carburetor adjustment is needed not only before the initial implementation, but also when any differences in its operation are detected. Before working with a chainsaw, do not forget to break it in.

Components of a carburetor

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

The foundation. This is a special tube that visually resembles an aerodynamic design. Air passes through it. A damper is located in the transverse direction in the middle of the pipe. Its position can be changed. poulan 2150 chainsaw adjustment - forum. The more it is extended into the passage, the less air enters the engine.
Diffuser. This is the narrowed part of the tube. With its help, the air supply speed is increased precisely in the segment where the fuel comes from.
Channels for fuel supply.The fuel mixture is contained in the float chamber, then passes into the jet, from which it flows into the atomizer.
float chamber. It is a separate structural element, reminiscent of the shape of the tank. Chainsaw device poulan 2150; poulan 2150 chainsaw carburetor adjustment; instructions for working with the poulan 2150 saw. Designed to constantly maintain the optimum level of the fuel fluid before entering the channel from which air enters.

Looking for cheaper models, but reliable and time-tested? Pay attention to Russian-made chainsaws.

Or look at foreign chainsaw manufacturers such as Stihl.

Each owner of a carburetor should have the necessary tools to make adjustments to this system. There are three adjustment screws that are located on the body of the device. They have their own markings:

L - screw for correcting low speed.
H - screw for adjusting high speed.
T - regulates idling, 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 up about 10 minutes before repair, and turns off at the start of work (see how to start a chainsaw).
Check and clean the air filter.
The chain is stopped by turning 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. You need a tachometer. It determines the presence of a violation in the operation of the carburetor. When turning the screws, the sound should be perfect and absolutely even. If squealing notes are noticed, then the mixture is oversaturated.

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

To complete the carburetor tuning procedure successfully, You need to read the instruction manual beforehand. specific model to identify additional features of device settings.

The adjustment screws for the highest and lowest speeds should be turned clockwise until the highest resistance is met. When the screws reach the stop, you need to move them in the opposite direction and leave when passing 1.5 turns.

The engine turns on at medium speed and it warms up for about 10 minutes. The screw responsible for adjusting the idle speed must move clockwise. Another adjustment of the https saw: resuscitation of the 2150 2150 chainsaw 2150. It is released only when the engine enters the stable operation mode. 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, you must immediately bring the adjusting screw clockwise to the stop. Sometimes the chain starts to move. In this case, turn the adjusting screw in the opposite direction.You need to do a little research. Device acceleration is initiated. It is necessary to evaluate the serviceability of the engine during the maximum speed. poulan chainsaws. Carburetor adjustment. Poulan 2150 when you press the accelerator, the speed quickly increases to 15,000 rpm. If this does not happen or the increase in speed is too slow, the screw marked L must be used. It turns counterclockwise.Moderate movements must be observed, since the turn cannot be more than 1/8 of a full circle.To limit this figure, you need to use a screw marked H. To increase the number of revolutions, turn it clockwise, and to reduce them in the opposite direction. The maximum frequency should not exceed 15000 rpm. If this indicator is made larger, the engine of the device will wear out, which will lead to problems in the ignition system. When rotating this screw, the ignition processes of the device must be taken into account. Advantages, disadvantages, price, technical specifications, analogues, adjustment and reviews of the owners of the poulan 2150 chainsaw. If the slightest failures appear, then the maximum speed value must be reduced.Before this procedure, it is necessary to perform a full adjustment of the carburetor components when operating at maximum speed. Next, you should check the operation of the device in idle cold mode. When the correct parameters are reached when adjusting, you can see the exact correspondence of the carburetor design to the following criteria:

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

Chainsaw Accelerator

When even a slight pressure on the accelerator is carried out, the engine is gaining momentum at an accelerated pace. With a gradual deepening of the pressure, you can notice that the engine speed increases commensurately, reaching the maximum allowable values.
When the engine is running, you can compare its sound with a four-stroke device.

If there are violations in the given parameters or the device was not fully adjusted, you need to perform the main setup step again. Repair of the poulan chainsaw diagnostics and adjustment of the chainsaw, poulan p 2150. Sometimes the actions are not performed correctly. 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.

Removing the Top Cover

The top cover is removed. To do this, unscrew the 3 bolts holding it in a circle.
The foam rubber is also removed, as it is the upper part of the filter that conducts air.
The fuel hose is removed.
The drive thrust is displayed immediately on it.
The end of the cable is disconnected.
The petrol hose can be completely removed by systematically pulling it off the fitting.

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

To properly set up 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 running for several hours in order to accurately set your own parameters. Sometimes work is done once after ten minutes of engine operation, however, many Chinese-made models require special handling.

Adjustment procedure:

Activities start in idle mode. With the help of adjusting screws, you need to achieve a systematic increase in engine speed, so you should first let it work 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 outer screws to the optimal position so that the chain remains stationary.
Switching to medium speed. Sometimes the engine will smoke. This defect can be eliminated by tightening the screw to supply a leaner fuel mixture.

The chainsaw should work for several hours in 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 are eliminated and the optimal settings for supplying correctly concentrated fuel are set, the process of setting up the device can be considered completed.

Take a look at the video:

In order for the chainsaw to work properly, you need to carefully carry out the work of adjusting the carburetor in exact accordance with their order. If there are any malfunctions in the functioning of the device, you must independently perform its complete disassembly. In most cases, replacement of any parts that have become unusable is required.

With a constant check of the quality of the carburetor settings and the implementation of timely actions to improve its operation, there are no problems with the chainsaw.
