  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.
