      Christopher BassAug 22, 2025
      If your Toro Lawn Mower engine won't start, starts with difficulty, or stops running, several factors could be at play. First, ensure the fuel tank isn't empty and the shut-off valve is open by filling the tank and opening the valve. Then, make sure the choke is engaged by moving the choke lever to the choke position. Check that the spark plug wire is securely connected to the spark plug. Inspect the spark plug itself; if it's damaged or improperly gapped, replace it with a new one. Also, a dirty air cleaner can cause issues, so service the air cleaner element. Finally, a clogged fuel filter can be the culprit, so replace it if necessary.
