Chainsaw give the gas stalls cause

Under load

In situations where the device stalls under load, the problem may be with the gas tank or filters. Check fuel quality and change filter.

Often the saw does not pick up speed due to the fact that the mixture poured into the gas tank has a low octane number. There is not enough power, sufficient warming up does not work, the chainsaw stalls under load.

Often component malfunctions lead to the fact that the device stalls under load. Hoses, seals, gaskets should be checked for suction. If the parts are defective, you can try to fix them or replace them.

What to do

If you find a malfunction, you can try to fix it yourself. If you cannot fix the device with your own hands, contact a specialist. The master will inspect the device, make a professional repair. This will avoid the risk of damaging the tool while trying to fix it yourself. Methods for eliminating dysfunctions depend on which part turned out to be faulty, due to which the operation of the saw was disrupted.

If the chainsaw starts up and immediately stalls, it is often caused by a lack of fuel. The amount of fuel fluid in the gas tank should be monitored, the device should be refilled in a timely manner.

It is important to operate the tool correctly by following the instructions. The use of the chainsaw for other purposes may impair the quality of the cut, lead to breakage, damage to the device.

New vehicles can be slow to start even with an easy start system. After a while, this problem is eliminated by itself. If a person has doubts about the serviceability of the device, it is recommended to consult a master.

A chainsaw is a household tool that, during its operation, lends itself to intense stress. Over time, many parts and mechanisms of the saw cannot withstand increased wear and fail. The first sign of serious damage to a garden tool appears even when its engine does not start. In this case, the first thing the operator has to do is find the cause of the breakdown and quickly fix it.

The chainsaw starts and the gas stalls

Any tool can break and the Stihl MS 180 chainsaw is no exception. Today we will try to understand such issues as: why the chainsaw stalls when the speed increases, also at idle and at full speed. Consider the options for diagnosing and eliminating malfunctions associated with this behavior of the Stihl 180 chainsaw.

When tilted

If the saw does not develop speed when tilted, shuts down, stops working, you need to check the fuel level in the tank. If it is not too high, the tilted device is not supplied with sufficient fuel because the fuel pipe is above the mixture level.

The main reason for this breakdown must be sought in the carburetor that was initially incorrectly tuned by the operator. If the tool picks up speed and stalls, then, most likely, due to mechanical shock or increased vibration, the factory settings of the fuel assembly adjusting screws have been violated. To solve a common problem that causes your tool to stall when heated, you need to adjust the carburetor.

If, after adjusting the carburetor, the garden tool stalls under load, then you need to carefully inspect the pipes through which the fuel circulates. If a hole has formed in one of them, then the fuel will not be able to fully enter the internal combustion engine cylinder. Because of this, the garden tool will be switched off randomly during the revs up.

Often, a chainsaw stalls when you give it gas, due to a violation of the throughput of the air filter. To solve the problem of an arbitrary shutdown of the engine to a hot one, it is enough to rinse the element and the space under it with clean gasoline. Then you need to reinstall the filter and again carefully check the operation of the garden tool.

What to do if the chainsaw stalls when you press the gas?

If the chainsaw used on the farm or on felling the forest works normally at idle, but stalls under load, then this, in most cases, may indicate two common malfunctions. The first common cause of failure is a clogged air or fuel filter. To inspect the parts, you will need to remove the standard protective plastic cover of the saw body. Thorough rinsing in clean gasoline will help to clean the filter elements. If the filters cannot be cleaned, then they must be replaced.

Often the chainsaw heats up and stalls due to a faulty fuel pump. It works under the influence of gears, which wear out quickly during intensive work. Replacing faulty gears or the entire pump will help to solve the problem.

In order to prevent such problems in the future, you need to carefully approach the choice of the components of the fuel mixture for refueling the chainsaw. The gasoline used must only be of the octane rating specified by the garden tool manufacturer. When choosing an engine oil, the saw operator should give preference to products from those brands that produce oils with all the additives necessary for stable tool performance.

To the cold

The reason why the device does not start on a cold one is often a violation of the engine start sequence.

You should read the instructions: manufacturers indicate how to properly start the chainsaw.

To enrich the fuel, you must first close the choke. After that, fuel is sucked in. For this, a special primer is used. Then turn on the ignition. Several strokes of the starter must be made before the engine flashes for the first time. The shutter opens and the device starts up. If the sequence is violated, a step is skipped, incorrect operation is possible.

If the chainsaw stops starting, the likely cause is a problem with the fuel system. Starting problems can occur due to improperly adjusted carburetor, blockage in the line and fuel filter. The quality of the fuel also matters. If the fuel is diluted with water, the appliance does not start well or does not work at all. The mixture must be fresh.

A possible cause of a problem starting is an engine malfunction. Wear or breakdown of a part leads to undesirable consequences: a decrease in compression in the cylinders and other troubles. With such problems, it is recommended to contact a specialist, since it is difficult to diagnose and fix a breakdown on your own.

Why does the chainsaw stall when you press the gas

Let’s say the chainsaw works normally at idle, but when the gas is pressed sharply, it stalls. What could be the reason? It is immediately clear that this is not about the ignition (no spark), since if the ignition is faulty and there is no spark, the tool would simply not start. This means that the fuel system remains.

There are a lot of malfunctions of the fuel system and to determine the exact reason why the Stihl 180 chainsaw stalls when you press the gas, you need to carry out a complete diagnosis. We recommend reading about common malfunctions of the Stihl 180 chainsaw and their elimination.

Air filter dirty

It is quite easy to make sure that the air filter is dirty. You just need to remove it and start the chainsaw without it. if the saw works fine, then it’s in it and it just needs to be changed or washed, depending on its type. And do not be afraid that the chainsaw will work for a while without dust protection. if there is no dust cloud around you, then everything is fine.

So, remove the air filter. To do this, you need to remove the cover from the rear upper part of the chainsaw, which is fastened either with screws, or simply with some kind of lock that you just need to turn or snap off.

If the saw operates normally when the filter is removed after starting up, then it is dirty.

The air filter is either felt or nylon. The first resembles cotton wool or synthetic winterizer, and the second looks like a fine mesh of nylon threads stretched over a plastic case. Felt needs to be changed to a new one, but nylon can be simply washed in soapy water, dried and put back in place.

Well, then we calmly use the chainsaw.

Localization of problem areas:

Filters are often clogged, especially when the chainsaw is used almost daily. The air filter can be detached and washed under warm running water. Dry thoroughly before inserting into place.

If, after disconnecting the fuel hose from the carburetor, no fluid flows out of it, then it is clogged. It can be cleaned or replaced with a new one.

With frequent use of the tool, the gasoline pump may be damaged. After all, every detail has its own expiration date. It should be replaced or contact a service center.

Why does a chainsaw stall under load

Sometimes the saw will not function properly under load. This is most often caused by improper adjustment or leaks in the carburetor. In addition, air leaks through the carburetor gasket or crankshaft oil seals may be the cause of this problem. A tool that is unable to function under load also cannot maintain idle speed reliably.

Diagnostics begins with checking the carburetor and crankcase for leaks. If air leaks through the crankshaft oil seals, they need to be replaced. If air leakage in the carburetor is detected, the installation of a repair kit of gaskets is required to solve the problem.

If these actions did not lead to the desired result and the crankcase with the carburetor is tight, then the carburetor needs to be adjusted.

If a Husqvarna chainsaw stalls under load, then for any deviations in the functioning of the engine, you should first of all check the impulse hose, since this is the most common cause of breakage of this brand of chainsaws.

Why the chainsaw stalls, the main reasons.

Fuel filter dirty

If the option with an air filter did not suit you, then we try to change the fuel one. It is located in the gas tank and is attached to the hose through which fuel is taken from the tank.

This hose must be gently pryed with something and removed from the gas tank its edge, on which the filter is fixed. Here, the option with work without a filter, as in the case of an air filter, is better not to apply, since you cannot know for sure if there are any unnecessary impurities in the fuel.

Fuel filter

Therefore, we simply change the fuel filter to a new one and try to work. If everything is fine, then congratulations. you have found the reason.
