How to troubleshoot a Wen DF1100 when the engine will not start?
- EErnest WellsJul 28, 2025
If your WEN Inverter engine won't start, begin by ensuring the engine switch is set to ON and the fuel valve is also in the ON position. Check the oil level and add or replace oil if it's low. Make sure the engine has fuel; if it does, drain the tank and refill with fresh fuel if the existing fuel is old or contaminated. Inspect the spark plug for dirt or damage, cleaning or replacing it as needed. Lastly, if the carburetor is air locked, shut off the fuel valve, remove the bolt from the bottom of the carburetor, take off the carburetor bowl to allow it to reset, then replace the bowl and reinstall the bolt.
