What to do if my Toro Lawn Mower engine does not start, starts hard, or fails to keep running?
- JJeffery HintonAug 13, 2025
If your Toro Lawn Mower engine is not starting, starts with difficulty, or doesn't stay running, check the following: ensure the fuel tank is full; make sure the choke is on; verify the air cleaner is not dirty (clean or replace it if it is); check that the spark plug wire(s) is securely connected; inspect the spark plug(s) and replace if pitted, fouled, or incorrectly gapped; and ensure the oil level in the crankcase is adequate, adding oil if low. Also, make sure that you are using the proper fuel type. If there is incorrect fuel, drain the tank and replace it with the proper type. If you find dirt in the fuel filter, replace it. For issues related to dirt, water, or stale fuel in the fuel system, contact an Authorized Service Dealer.
