Why doesn't the gas trimmer start?

The owner of the suburban area can not do without a brushcutter or trimmer. But in the process of its operation, situations may arise when this unit for some reason ceases to start. And there can be many reasons for this. Let’s find out why a gas trimmer does not start.

Why the trimmer does not start. the reasons

To determine why the gas trimmer does not start well or stalls constantly, it is necessary to consistently check the operation of all the main components of the unit. It is especially important to do this after prolonged storage of the brushcutter. So, the main reasons for this trimmer behavior are as follows:

  1. The culprit that the brushcutter does not start may be a poor-quality oil-gasoline fuel mixture. It must be prepared strictly according to the instructions. Saving here is not at all appropriate, since it can lead to failure of the entire piston group of the trimmer. Do not cook too much fuel mixture, as excess gasoline will lose its quality over time.
  2. You should be aware that gas trimmers of brands such as Stihl, Husgvarna and some others will not start if they are filled with cheap gasoline with a low octane rating. Therefore, for such units it is necessary to use only high-quality high-octane fuel.
  3. If the trimmer stalls immediately at start-up, then it may have a candle in it. In this case, it is necessary to unscrew it and dry thoroughly for half an hour. Then drain the excess fuel that is in the chamber, clean the candle from soot, put it in its place and try to start the brushcutter.
  4. If your new gas trimmer does not start, the cause may be a lack of spark. And this happens because the nest where the candle is located is dry and the fuel does not light up. Lightly moisten the threaded connection of the candle with a few drops of gasoline.
  5. The gas trimmer may stall due to clogged air or fuel filters. It is best to replace such items with new ones.
  6. The exhaust duct and breather can also become clogged. After cleaning these trimmer elements, you can start the unit without any problems.
  7. Another reason why the gas trimmer does not start, even when there is a spark, may be a clogged carburetor. To clean the channels and jets, it is necessary to blow them with compressed air using a compressor.

    Most often this happens for beginners, when the first run is passed “clap” on a closed air damper and continue to pull the starter handle, respectively, there is a lot of gas in the combustion chamber, and not enough air prevents the gas from igniting.

    The problem is solved simply:

    1. With a candle key, unscrew the candle and check its condition. If the candle is wet and there is a spark, then it was flooded. We open the air damper, turn on the switch button, squeeze the gas “all the way” and start it. Excess gasoline should come out of the exhaust saw and the saw will start.
    2. With a candle key, unscrew the candle and check its condition. If the candle is wet and there is a spark, then it was flooded. Turn the chainsaw with the candle hole down and rotate the starter ten times, while excess fuel will flow out of the engine cylinder. Then wipe dry (bake) the candle, or replace it with a new one and try to start the engine exactly following the operating instructions. If the spark plug is completely dry, this means that no fuel is entering the engine. And since it is in the tank, there is probably a problem in the carburetor. You can draw a little mixture into the syringe, inject it into the cylinder, twist the spark plug and try to start the engine. But if the engine starts up and stalls immediately, then the problem remains and you need to contact a service center.
