How to fix a White Outdoor AutoDrive LT 18G Lawn Mower that won't start?
- A
  Amy ReyesAug 13, 2025
  If your White Outdoor Lawn Mower engine won't start, several factors could be at play. Make sure the PTO lever is disengaged (OFF), and the parking brake is engaged. Check that the spark plug wire(s) are properly connected. Ensure the throttle control is in the correct position, using the CHOKE if available, and that the choke is activated. The fuel tank should be filled with fresh gas (less than 30 days old), and the fuel line should be clear. A faulty spark plug may also be the culprit, so clean, adjust the gap, or replace it. Lastly, if the engine is flooded, crank it with the throttle in the FAST position.

Why does my White Outdoor AutoDrive LT 18G engine run erratic?
- L
  Laura ThompsonAug 16, 2025
  If your White Outdoor Lawn Mower engine runs erratically, it might be due to a few reasons. First, ensure the throttle lever is in the FAST position, as running with the CHOKE applied can cause this. Check the spark plug wire to make sure it's connected and tight. A blocked fuel line or stale fuel can also lead to erratic running, so clean the fuel line and fill the tank with fresh gasoline. The vent in the gas cap could be plugged, so clear it or replace the cap if damaged. Water or dirt in the fuel system can also cause issues, so drain the fuel tank. Lastly, check the air cleaner and replace the cartridge/element or clean the pre-cleaner if necessary.

What to do if my White Outdoor Lawn Mower will not mulch grass?

  If your White Outdoor Lawn Mower is not mulching grass effectively, there could be several reasons. Check that the engine speed is set to FAST. Avoid mowing when the grass is wet, as this can hinder mulching. If the grass is excessively high, mow once at a higher cutting height before mowing again at the desired height, or try making a narrower cutting swath. Finally, ensure the blade is sharp; if it's dull, sharpen or replace it.

  If your White Outdoor Lawn Mower is producing an uneven cut, several factors could be the cause. The deck might not be balanced properly, so perform a side-to-side deck adjustment.

  If your White Outdoor Lawn Mower is vibrating excessively, it could be due to the cutting blade being loose, unbalanced, or damaged. Try tightening the blade and spindle first. If that doesn't solve the problem, balance the blade. If the blade is damaged, replace it.
