Why my MTD Lawn Mower engine runs erratic?
- NnarmstrongJul 29, 2025
If your MTD Lawn Mower engine is running erratically, there could be several reasons. Ensure that the throttle control is not in the CHOKE position. Check the spark plug wires to ensure they are connected and tight. A blocked fuel line or stale fuel can cause this issue, so clean the fuel line, fill the tank with fresh gasoline, and replace the fuel filter if equipped. Also, check the vent in the gas cap for blockage and clear it, or replace the cap if it's damaged. Water or dirt in the fuel system can also cause erratic running; drain the fuel tank and refill it with clean, fresh gasoline. Finally, a dirty air cleaner can contribute to this problem, so replace the air cleaner paper element or clean the foam pre-cleaner if your mower has one.
