What to do if my Toro 72907 engine does not start, starts hard, or fails to keep running?

Several factors can cause this issue. First, ensure the fuel tank isn't empty and the fuel-shutoff valve is open. Check that the oil level in the crankcase is sufficient. Make sure the throttle control is midway between the slow and fast positions. Replace the fuel filter if it's dirty, and clean or replace the air-cleaner element if it's dirty. Inspect the seat-switch indicator and replace the seat if necessary. Check the spark-plug wire connection, and adjust or replace the spark plug if it is fouled or improperly gapped. Also, check the electrical connections for good contact, cleaning the connector terminals thoroughly with electrical-contact cleaner, apply dielectric grease, and make the appropriate connections.
