Brushcutter that stalls at idle: common problems
It is common for a brush cutter to stall at idle and most of the time, it is a minor failure, simple and quick to repair yourself. All you need to do is look at the carburetor and what makes it work. In case of doubt or for any question related to the maintenance and repairs of your DIY garden tools, our specialists are there to answer you.
Adjustment screw is loose causing engine stall
The most common consequence of a brushcutter stalling at idle is due to an adjusting screw (also called a set screw). wealth) and / or vidle speed of the carburetor that is loose. Simple fault to identify and easy to repair, it will only take a few seconds to tighten the faulty screw and be able to enjoy your gardening tool again. No need to worry, it's quite common as these screws tend to come loose. You may be able to repair without tools, just by tightening the screw with your fingers. But for better rendering, we still advise you to use a screwdriver.
Brushcutter's air and / or fuel filters are not clean
Another frequently encountered problem that seems logical enough for a brush cutter that stalls at idle is carburetor failure. It is easy to verify if this is the problem with a simple visual check before any more complex repair undertaking. Check if the spark plug is in good condition and if the fuel filter et the air filter are clean. It would be pointless indeed to change a spark plug if the air filter is clogged or faulty. Correcting these problems before any other is therefore the priority. Yes your brush cutter smokes, it may be related to another problem.
The carburetor: the first cause of failure of a brush cutter that stalls at idle
After any failures or problems with the adjustment screws and filters, check the condition of the tank carburetor. The cap must be in good enough condition to do its sealing job. As you will have understood, the carburetor is the main element of your brushcutter to be checked in the event of a problem as well as all the surrounding elements that allow it to operate correctly. Once all of this has been analyzed, checked and, if necessary, repaired, your device should function normally. However, there may be other issues that persist, less well known and more complex.
Brushcutter that stalls at idle: the rarer problems
Like any mechanical tool, a brush clearing device can be subject to complex breakdowns, which require special knowledge and know-how. After you have inspected (and corrected if necessary) the above points and if the problem persists, then you may be dealing with one or more more difficult to determine problems.
Engine stalls due to throttle stop screw
To operate properly at idle, the engine speed of your device must be high enough. This system will operate thanks to a throttle stop screw which has the task of accessing the opening of the throttle to run the engine. The engine speed must therefore be high enough to operate the device at low speed but also low enough so that the engine does not stall. A failure which would be caused by this screw is possible but rarer; it must nevertheless be taken into consideration.
The membrane of the brush cutter is perforated
The membrane has the function of supporting the fuel pressure in the carburetor. This rubber membrane can be damaged, following a perforation for example. If this is true and this membrane is defective, then the engine of your brushcutter will no longer be able to maintain the fuel under the necessary pressure and it will stall at idle. It should be changed before any new use.
Defective screws that results in idle failures
As we saw above, the various screws can be loosened and for several reasons, cause failures. If most of the time it is enough to tighten them to remedy the problem, it may happen that they must be changed because they are in poor condition or defective. It is then necessary to find identical screws (of the same brand or the same manufacturer preferably) and to replace them. This may require a certain know-how and specific tools. Call a specialist for any breakdown that you find too complex to repair yourself so as not to further damage your machine.
