Why won't my Toro Lawn Mower engine start?
- Jjoel28Aug 25, 2025
If your Toro Lawn Mower engine won't start, starts with difficulty, or stops running, there are several potential causes. First, ensure the fuel tank isn't empty and the fuel shutoff valve is open. Check that the oil level in the crankcase is adequate. For a cold engine, the choke should be in the 'ON' position, while for a warm engine, it should be 'OFF,' and the throttle control should be midway between 'SLOW' and 'FAST'. Other causes could be a dirty fuel filter (replace it), a dirty air cleaner (clean or replace it), or a faulty spark plug (clean, adjust, or replace it). Also, ensure the spark plug wire is connected and the seat switch is functioning properly. Check the electrical connections for corrosion or looseness, clean them, and apply dielectric grease before reconnecting.
