How to start a Stihl FS 491 C-M Trimmer when the engine won't start?
- NnburnsAug 6, 2025
If your Stihl Trimmer engine won't start, it could be due to several reasons. First, ensure you have enough fuel mix in the tank; if not, refuel it. If the carburetor is too hot, allow the trimmer to cool down and depress the manual fuel pump at least 10 times before attempting to start it. Also, if the carburetor has iced up, allow the trimmer to warm up to +10°C.
