Why won't my Toro 74790 Lawn Mower engine start?
- HhenrywrightAug 18, 2025
If your Toro Lawn Mower engine won't start, has difficulty starting, or stalls frequently, several factors could be at play. First, ensure the fuel tank isn't empty by filling it. Then, check that the choke is activated by moving the choke lever to the ON position. A dirty air cleaner can also cause issues, so clean or replace the air-cleaner element. Make sure the spark-plug wire(s) is securely connected to the spark plug. Inspect the spark plug(s) for pitting, fouling, or incorrect gaps, and replace if necessary with a correctly gapped spark plug(s). Also, check for a dirty fuel filter and replace it if needed. Ensure that you are using the correct fuel type; if not, drain the tank and refill with the proper fuel. Finally, verify the oil level in the crankcase and add oil if it is low.
