  If your Husqvarna Trimmer engine starts and then stops, the issue might be due to incorrect fuel type. In this case, empty the fuel tank and refill it with the correct fuel. Another potential cause is a clogged fuel filter, which requires replacement. Also, check the idle speed, as it may not be correctly adjusted; adjust it using the idle speed screw T.

  If your Husqvarna Brush Cutter fails to start, begin by checking that the stop switch is in the start position. Binding pawls can also prevent starting, so adjust or replace them. Clean around the pawls. Ensure you're using the correct fuel type; if not, drain the incorrect fuel and use the right one. Adjust the idling speed with the T-screw. Inspect the spark plug to ensure it is dry and clean. Also, verify the spark plug gap is correct and that the spark plug is fitted with a suppressor. Retighten the spark plug if it is loose. Lastly, a clogged fuel filter can cause starting failure, so replace it.
