Petrol Trimmer Does Not Start There Is A Spark

Why does the trimmer not start?

  • To determine why the gasoline trimmer does not start well or constantly stalls, it is necessary to consistently check the operation of all the main components of the unit. This is especially important after long-term storage of the lawn mower. So, the main reasons for this behavior of the trimmer are as follows:

    1. The culprit for the lawn mower not starting may be a poor-quality oil-gasoline fuel mixture. It must be cooked strictly according to the instructions. Saving is not at all appropriate here, since it can lead to the failure of the entire piston group of the trimmer. Do not prepare too much fuel mixture, as excess gasoline will lose its quality over time.
    2. Be aware that petrol trimmers of brands such as Stihl, Husgvarna and some others will not start if they are filled with cheap petrol with a low octane number. Therefore, for such units it is necessary to use only high-quality high-octane fuel.
    3. If the trimmer stalls immediately upon start-up, it may have a flooded candle. In this case, you need to unscrew it and dry it thoroughly for half an hour. Then drain the excess fuel in the chamber, clean the candle from carbon deposits, put it back and try to start the lawn mower.
    4. If your new gasoline trimmer won’t start, there may be a lack of spark. And this happens because the socket where the candle is located is dry and the fuel does not ignite. Lightly moisten the thread of the spark plug with a few drops of gasoline.
    5. The gasoline trimmer may stall due to clogged air or fuel filters. It is best to replace such elements with new ones.
    6. The exhaust port and breather can also become clogged. Having cleaned these trimmer elements, it will be possible to start the unit without any problems.
    7. Another reason why the petrol trimmer won’t start, even when there is a spark, may be a clogged carburetor. To clean the ducts and nozzles, blow them out with compressed air using a compressor. Can be used to clean the carburetor and special rinse.
    8. If the carburetor gaskets are worn out, replace them. And if the tightness of this device is broken, you will have to identify the faulty carburetor part and replace it.
    9. The trimmer may not start due to wear on the piston group. However, it is better to change such parts of lawn mowers in a service center.

    Firstly: try to clean the carburetor if it gets dirty, it will damage the mower.

    There are several reasons why the trimmer will not start. I will list the main ones:

    • Bad fuel. Each trimmer model requires petrol with a specific octane rating. Check the instructions for use and make sure you fill in exactly the required.
    • Flooded candles. At the same time, I advise you to check the candles for performance. Sometimes even new (in a box) candles may be inoperable or defective.
    • The fuel mixture does not enter the carburetor. Pump her up a little.
    • The ignition coil is out of order.
    • Muffler clogged. It is necessary to free it from carbon deposits. To do this, carefully disassemble and clean (you can burn on a gas burner).

    Usually trimmer we have did not start after winter, and we used to take the trimmer to the workshop almost every spring, where it was repaired to us. But, once, a knowledgeable person advised us, firstly, never to leave gasoline in the trimmer for the winter, because old gasoline can be the reason that the trimmer does not start, and he also said that it is necessary for the trimmer plant to pump the carburetor with a fuel mixture. After we began to follow these rules, our problems with the trimmer disappeared.

    First of all, you can see the candle. If necessary, replace it, making sure that the spark plug is not broken and gives a normal spark. The next problem will be lurking in the fuel system. As mentioned above, we check the tightness, then we check the fuel filter, change it if necessary. We clean the carburetor, see the effect. It may be necessary to dig into the ignition system, adjust. To check the fuel system, you can pour a few grams directly into the cylinder through the plug screw holes, screw in the plug and try to start. At least the trimmer should make sounds of the engine running for 1-2 seconds and some smoke should fly out of the muffler.
