Why is my Toro Lawn Mower engine losing power?
- SScott BrownSep 3, 2025
If your Toro Lawn Mower engine is losing power, consider these potential causes: excessive engine load, which can be resolved by reducing ground speed. A dirty air cleaner can restrict airflow, so clean it. Low oil level in the crankcase can also cause power loss, so add oil. Check for obstructions in the cooling fins and air passages and remove them. Inspect the spark plug(s) for damage or incorrect gap and replace if necessary. If there is incorrect fuel in the fuel tank, drain the tank and replace the fuel with the proper type. Finally, if the fuel filter is dirty, replace it.
