Why won't my Toro Lawn Mower engine start?
- B
  brenda73Aug 4, 2025
  Several factors can prevent your Toro Lawn Mower engine from starting. First, ensure the fuel tank isn't empty by filling it. If it is not the reason, make sure the choke is on. A dirty air cleaner can also be the culprit, 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 needed. Additionally, ensure the fuel filter is clean, and the fuel tank contains the correct type of fuel. Finally, check that the oil level in the crankcase is sufficient and add oil if needed.

Why does my Toro 74627 Lawn Mower engine lose power?
- K
  Krystal ClarkAug 8, 2025
  If your Toro Lawn Mower engine is losing power, consider these possible causes: The engine load might be excessive, so reduce ground speed. A dirty air cleaner can also cause power loss, so clean the air cleaner element. Check the oil level in the crankcase and add oil if it's low. Make sure the cooling fins and air passages under the engine blower housing are free from obstructions. Inspect the spark plug(s) and replace them if pitted, fouled, or incorrectly gapped. Finally, if there is incorrect fuel in the fuel tank, drain the tank and replace the fuel with the proper type.
