Why won't my Craftsman C459-36426 Lawn Mower engine start?
- D
  Daniel WilsonAug 15, 2025
  If your Craftsman Lawn Mower engine won't start, several factors could be at play. First, ensure the blade control is engaged. Next, check that the spark plug boot is securely connected. If these aren't the issue, the fuel tank might be empty or contain stale fuel, requiring a refill with fresh gasoline. If your mower has a primer, make sure you've primed the engine correctly. A faulty spark plug could also be the culprit, so clean, adjust the gap, or replace it as needed. In case the engine is flooded, wait a few minutes before attempting to restart. Finally, a blocked fuel line could be the reason, and you should contact your Sears Parts & Repair Center to have it cleaned.

Why does my Craftsman C459-36426 engine run erratic?

  Justin RiceAug 22, 2025
  If your Craftsman Lawn Mower engine runs erratically, there are several things to check. Start by ensuring the spark plug boot is securely connected and tightened. Stale fuel can also cause this issue, so replace it with clean, fresh gasoline. Make sure the vent in the gas cap isn't plugged; clear it if necessary. Water or dirt in the fuel system could also be the problem; run the engine until it stops due to lack of fuel, then refill with fresh fuel. A dirty air cleaner might be the cause, so refer to the Air Cleaner section in the Engine Maintenance section. Lastly, a blocked fuel line could be the culprit, in which case you should contact your Sears Parts & Repair Center to have it cleaned.

  If your Craftsman Lawn Mower wheels will not propel, the belt may not be installed properly, so check the belt for correct pulley installation and movement. Debris might be clogging the drive operation, so clean it out. The belt could also be damaged or worn, so inspect and replace it if necessary.

  Kara OrtizAug 28, 2025
  If your Craftsman Lawn Mower idles poorly, the spark plug might be fouled, faulty, or have a gap that's too wide. Reset the gap or replace the spark plug. Alternatively, the air cleaner could be dirty, so refer to the Air Cleaner section in Engine Maintenance.

What to do if my Craftsman Lawn Mower will not mulch grass?
- V
  Vickie StanleySep 1, 2025
  If your Craftsman Lawn Mower is not mulching grass effectively, it could be due to a few reasons. Avoid mowing when the grass is wet; wait for it to dry. If the grass is excessively high, mow it first at a higher cutting height, then mow again at the desired height, or narrow the cutting path. A dull blade can also cause poor mulching, so sharpen or replace the blade.
