  If your Toro Lawn Mower engine doesn't start, starts hard, or fails to keep running, several factors could be at play. Start by checking if the fuel tank is empty and fill it if needed. Ensure the fuel-shutoff valve is open. Verify the oil level in the crankcase and add oil if it's low. Make sure the throttle control is positioned midway between the SLOW and FAST settings. Check and replace the fuel filter if it's dirty. Inspect the air cleaner and clean or replace the element if it's dirty. Also, make sure the spark-plug wire is connected, and clean, adjust, or replace the spark plug if it's faulty. Finally, check the electrical connections for good contact, cleaning the connector terminals if necessary.
