Why does my MTD 420cc Engine fail to start?
- CColleen SmithJul 27, 2025
Your MTD Engine might fail to start due to several reasons. It could be flooded, in which case you should wait at least 10 minutes before attempting to start it again. Other potential causes include a disconnected spark plug wire (connect it to the spark plug), an empty fuel tank or stale fuel (fill the tank with clean, fresh gasoline), the engine not being choked (choke the engine), a faulty spark plug (clean, adjust the gap, or replace it), or the throttle being in the stop position (move the throttle to the FAST/Run position).
