How to fix Toro 74938 Lawn Mower engine when it loses power?
- JJerry SmithAug 31, 2025
If your Toro lawn mower engine loses power, try reducing the ground speed, as the engine load may be excessive. Check and clean the air cleaner element if it's dirty. Ensure the oil level in the crankcase is sufficient. Clear any obstructions from the cooling fins and air passages above the engine. Also, inspect the fuel cap vent hole and clean or replace the fuel cap if it's plugged, and replace the fuel filter if it is dirty.
