What to do if my Toro TimeCutter Z5000 74391 engine will not start?
- RRobert PopeJul 26, 2025
If your Toro Lawn Mower engine won't start, starts hard, or fails to keep running, make sure the fuel tank isn't empty by filling it. Ensure the choke is on by moving the choke lever to the 'On' position. A dirty air cleaner can cause issues, so clean or replace it. Check the spark plug wire(s) and install them securely on the spark plug. Replace any pitted, fouled, or incorrectly gapped spark plugs with new ones. Also, replace the fuel filter if it's dirty. If there's incorrect fuel in the fuel tank, drain it and replace it with the proper type. Finally, ensure the oil level in the crankcase is sufficient by adding oil if needed. If the problem persists, it may be due to dirt, water, or stale fuel in the fuel system, and you should contact an Authorized Service Dealer.
