Why won't my Craftsman Lawn Mower engine start?
- D
  Deborah OrrAug 13, 2025
  If your Craftsman Lawn Mower engine won't start, several factors could be at play. First, make sure the blade control is engaged. Next, check that the spark plug boot is connected securely. If those aren't the issue, ensure your fuel tank isn't empty and that you're using clean, fresh gasoline. A faulty spark plug could also be the culprit—try cleaning, adjusting the gap, or replacing it. If the engine is flooded, wait a few minutes before attempting to restart. For a blocked fuel line, it is recommended to contact your Sears Parts & Repair Center to have it cleaned.

  If your Craftsman Lawn Mower engine is running erratically, start by checking the spark plug boot to ensure it's connected and tightened. Stale fuel can also cause issues, so refill the tank with clean, fresh gasoline. Make sure the vent in the gas cap isn't plugged, and if there's water or dirt in the fuel system, run the engine until it stops from lack of fuel, then refill with fresh fuel. For a blocked fuel line, it is recommended to contact your Sears Parts & Repair Center to have it cleaned. If the air cleaner is dirty, refer to the Air Cleaner section in Engine Maintenance.

  An uneven cut with your Craftsman Lawn Mower can occur if the wheels are not positioned correctly. Adjust the cutting height lever on the right front and right rear wheels to the same position. Also, a dull blade can cause an uneven cut, so sharpen or replace the blade.

  Mrs. Brooke RodriguezAug 25, 2025
  If your Craftsman Lawn Mower engine overheats, it could be due to a low engine oil level. Fill the crankcase with the proper oil. Another possible cause is restricted airflow, so clean the area around and on top of the engine.

  Excessive vibration in your Craftsman Lawn Mower can be caused by a loose or unbalanced cutting blade. Tighten the blade and adapter, and balance the blade. If the cutting blade is bent, replace it.

What to do if my Craftsman Lawn Mower will not mulch grass?
- M
  Matthew RyanSep 1, 2025
  If your Craftsman Lawn Mower won't mulch grass effectively, it might be due to wet grass. Avoid mowing when the grass is wet; wait until it's dry. Excessively high grass can also be a factor; mow once at a high cutting height, then mow again at the desired height, or make a narrower cutting path. A dull blade will also prevent mulching, so sharpen or replace the blade.

  If your Craftsman Lawn Mower idles poorly, it could be due to a spark plug that is fouled, faulty, or has a gap that's too wide. Reset the gap to .030” or replace the spark plug. If the air cleaner is dirty, refer to the Air Cleaner section in Engine Maintenance.
