Why Toro 74209 engine will not start?
- M
  Morgan KirkAug 18, 2025
  Your Toro Lawn Mower engine might not start due to several reasons. The fuel tank could be empty, so fill it with gasoline. Alternatively, the choke may not be on, so move the choke lever to the ON position. A dirty air cleaner can also prevent starting, so clean or replace the air cleaner element. Check if the spark plug wires are loose or disconnected and install them on the spark plug. Also, the spark plugs might be pitted, fouled, or have an incorrect gap, so install new, correctly gapped spark plugs. Finally, dirt in the fuel filter can be a cause, so replace the fuel filter.

  If the blades on your Toro Lawn Mower do not rotate, it could be due to a worn, loose, or broken drive belt, so install a new drive belt. Also, check if the drive belt is off the pulley and install the drive belt, checking the adjusting shafts and belt guides for correct position. The deck belt might be worn, loose, or broken, so install a new deck belt.

Why does my Toro Lawn Mower engine loses power?
- F
  francisryanAug 30, 2025
  Your Toro Lawn Mower engine might be losing power due to several reasons. The engine load could be excessive, so reduce the ground speed. A dirty air cleaner can also cause this, so clean the air cleaner element. Check if the oil level in the crankcase is low and add oil if needed. Also, ensure that the cooling fins and air passages under the engine blower housing are not plugged; remove any obstructions. Replace pitted, fouled, or incorrectly gapped spark plugs. Open the vent in the fuel cap if it's closed and replace the fuel filter if it's dirty.
