What to do if my Toro Z Master 77248 engine does not start?

If your Toro Lawn Mower engine won't start, starts with difficulty, or stalls, 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 sufficient. The throttle should be midway between the slow and fast positions. Also, a dirty air cleaner can cause this issue, so clean or replace it. Inspect the spark plug for fouling or improper gapping and adjust or replace it as needed. Make sure the spark-plug wire is connected properly. If there is dirt in the fuel filter, replace it. Finally, check the seat-switch indicator, and replace the seat if necessary.
