Why won't my Yard-Man YM25 engine idle?
- SStacy SmithSep 12, 2025
If your Yard-Man Trimmer engine won't idle, it could be due to a plugged air filter (replace or clean the air filter), old or improperly mixed fuel (drain the gas tank and add fresh fuel mixture), or an improper carburetor adjustment. If it is the carburetor, adjust according to the Carburetor Adjustment section.
