  If your Craftsman Lawn Mower engine won't start, several factors could be the cause. First, ensure the blade control is engaged. Check that the spark plug boot is connected securely. If the fuel tank is empty or contains stale fuel, refill it with fresh gasoline. Inspect the spark plug for faults and clean, adjust the gap, or replace if necessary. If the engine is flooded, wait a few minutes before attempting to restart it. If the fuel line is blocked, contact a 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 tightly connected. Replace stale fuel with fresh gasoline. Make sure the vent in the gas cap isn't plugged. If there's water or dirt in the fuel system, run the engine until it stops, then refill with fresh fuel. For a dirty air cleaner, refer to the Air Cleaner section in the Engine Maintenance part of the manual. If the fuel line is blocked, contact a Sears Parts & Repair Center to have it cleaned.

Why is my Craftsman C459-36479 Lawn Mower not mulching grass properly?
- J
  Julie NelsonAug 31, 2025
  If your Craftsman Lawn Mower isn't mulching grass effectively, it could be due to several reasons. Avoid mowing when the grass is wet; wait until it's dry. If the grass is excessively high, mow once at a higher setting, then again at the desired height, or reduce the cutting path width. A dull blade can also cause this issue, so sharpen or replace it.

  If your Craftsman Lawn Mower idles poorly, the spark plug may be fouled, faulty, or have a gap that is too wide. Reset the gap to .030” or replace the spark plug. Also, a dirty air cleaner can cause this issue. Refer to the Air Cleaner section in the Engine Maintenance part of the manual for cleaning instructions.
