    What to do if Husqvarna Trimmer starts but stops again?

      Lance GonzalezAug 23, 2025
      If your Husqvarna Trimmer starts but then stops, it could be due to several reasons. The fuel type might be incorrect, so you should empty the fuel tank and fill it with the correct fuel. Another cause might be a clogged fuel filter, which requires replacing the fuel filter. Additionally, the idle speed might not be correctly adjusted, so you should adjust the idle speed with the idle speed screw T. Finally, a clogged air filter could also be the cause, and cleaning the air filter should resolve the issue.

Alternatively, the starter pawls may not be moving freely; try removing the starter cover and cleaning around them. Refer to To clean the cooling system on page 25. Other potential causes include incorrect fuel type (drain and refill with the correct fuel), incorrect idle speed adjustment (adjust with the idle speed screw T), a dirty or wet spark plug (dry and clean it), an incorrect spark plug electrode gap (clean the spark plug, ensure the electrode gap is correct, and make sure the spark plug has a suppressor), a loose spark plug (tighten it), or a clogged f...
