What to do if my MTD Lawn Mower engine runs erratically?
- DdavidperryAug 17, 2025
Erratic engine performance in your MTD Lawn Mower can stem from a few common issues. Start by checking the spark plug boot to ensure it's firmly connected and tightened. A blocked fuel line or stale fuel can also cause problems; clean the fuel line and refill the tank with fresh gasoline. Make sure the vent in the gas cap isn't plugged. Additionally, water or dirt in the fuel system can lead to erratic running, so drain the fuel tank and refill it with fresh fuel. If the air cleaner is dirty, refer to the engine manual for cleaning instructions. Finally, ensure the choke is in the “OFF” position if your unit is equipped with one.
