Why Toro Riding mower engine will not start?
- QqmillerAug 15, 2025
Several factors can prevent your Toro Riding mower engine from starting. Ensure the fuel tank is full and the fuel shutoff valve is open. Check that the oil level in the crankcase is adequate. Position the throttle midway between the “SLOW” and “FAST” settings, and adjust the choke based on whether the engine is cold (ON) or warm (OFF). A dirty fuel filter can also be the culprit, so replace it if necessary. Other potential causes include a malfunctioning seat switch (check the indicator and replace if needed), corroded or loose electrical connections (clean and reconnect), a faulty spark plug (clean, adjust, or replace), or a disconnected spark plug wire (check the connection).
