What To Do When Petrol Trimmers Do Not Start?

The petrol trimmer is a surprisingly useful tool, with which you can mow not only a small lawn in front of the house but also a whole yard of considerable size. Unfortunately, in this world there is nothing eternal, but because you may be faced with the fact that petrol trimmers do not start.

It often happens that users of this kind of machines are trying to “save” by pouring into the tank not fuel with a normal octane number, but something incomprehensible that had been standing in a plastic canister for almost a decade.

The main thing. the fuel mixture!

In this case, the remnants of plastic dissolved in an aggressive environment create such terrible things in the combustion chamber that you will not be able to do without a complete selection of the mechanism. But you will forever remember how to store fuel properly.

What to do when exactly the fuel was normal, there is a spark, but the gas trimmer does not start? It is possible that you fill the candle with gasoline. In this case, it is necessary to turn it out, wipe it with a clean cloth and dry it. By the way, it will be quite useful to check the candle itself for performance.

Correctly make a cold start!

Often, petrol trimmers do not start after trying to “put into operation” after long-term storage. Failures with the launch, in this case, are often due to incorrect user actions.

If you are faced with this phenomenon, then during a cold start, you need to close the valve, and then pump a small amount of the fuel mixture into the carburetor. Then pull the starting handle to the feeling of resistance, then with sharp and vigorous movements start the trimmer.


There are not only situations when petrol trimmers do not start, but there are cases when, after starting, they work for a couple of seconds and then fade away. Once again, inspect the spark plug: if it is “thrown”, and this situation repeats even after it is wiped and dried, go to the “revision” of the air filter.

Most likely, it is entirely oiled and needs to be replaced. If everything is fine with the filter, it may be that the ignition coil is out of order.

In the case when gas trimmers do not start, and you have done all of the above, a silencer may be clogged. It must be dismantled, burned on the burner, after which the entire carbon can be easily shaken out.

Well, if even after such bullying your trimmer does not start, you can not do without disassembling the carburetor. It may very well be that the pinching of the needle in it is to blame for everything. In any case, the dismantling and washing of this whimsical mechanism certainly do not interfere.

In general, when the trimmer began to act up and stall, it is advisable to carry out complete prevention: completely change the fuel mixture, try another oil, and also change the candle without fail. Practice shows that in many cases, it is the cheap low-quality candles that are to blame.

We considered the most typical reasons for why the trimmer does not start. If the matter is in something more “exotic”, do not avoid going to a service center. Smaller and more obvious damage you will surely find yourself.
