Why does my Toro 74770 engine not start?
- BBrian LawsonAug 23, 2025
If your Toro Lawn Mower engine won't start, struggles to start, or stalls, several factors could be at play. First, ensure the fuel tank isn't empty by filling it. A dirty air cleaner can also cause issues, so clean or replace it. Check that the spark plug wire(s) is securely connected to the spark plug. Inspect the spark plug(s) for damage, and replace if necessary, ensuring correct gapping. Also, a dirty fuel filter can cause problems, so replace it. Finally, ensure the oil level in the crankcase is adequate by adding oil if needed.
