How to troubleshoot a starting problem in my AS MOTOR Trimmer?
- SShawn ThomasAug 14, 2025
If the AS MOTOR Trimmer engine doesn't start, several factors could be at play. First, ensure the accelerator lever is set to 'idle speed'. Check that the fuel valve is open (open both if there are two). The tank ventilation screw should also be open. Refill the fuel tank if it's empty. If the choke is open, close it. Make sure the spark plug connector is securely attached. If the engine is flooded from too many start attempts, remove the spark plug, close the fuel valve, start the engine several times to dry it out, and then reattach the spark plug. A dirty air filter can also prevent starting, so maintain the air filter. Inspect the spark plug for soot, damage, or an incorrect electrode gap; clean or replace it as needed. Finally, ensure you're using the correct spark plug connector.
