Why does my Toro LX460 engine run erratic?
- BBryan WrightAug 27, 2025
If your Toro Lawn Mower engine runs erratically, first ensure the Throttle/Choke Control is not in the CHOKE position. Check and tighten the spark plug wires, and make sure the fuel line is clean and the fuel is fresh (less than 30 days old). Also, check if the vent in the gas cap is plugged, and drain the fuel tank if there's water or dirt in the fuel system. Finally, inspect the air cleaner and replace the paper element or clean the foam precleaner if dirty.
