    Why Craftsman 247.372370 Lawn Mower engine fails to start?
    • T
      travisgibsonJul 31, 2025
      If your Craftsman Lawn Mower engine won't start, there are several potential causes. First, ensure that the blade control is engaged. Next, check that the spark plug boot is connected securely. Also, the fuel tank may be empty or contain stale fuel, so fill it with fresh gasoline. If your mower has a primer, make sure to prime the engine as instructed. A faulty spark plug could also be the culprit, so clean, adjust the gap, or replace it. If the engine is flooded, wait a few minutes before attempting to restart it. Finally, a blocked fuel line may be the issue.

    What to do if Craftsman Lawn Mower engine runs erratic?
    • C
      Christina MasseyAug 8, 2025
      If your Craftsman Lawn Mower engine is running erratically, start by checking the spark plug boot to ensure it is connected and tight. Stale fuel can also cause this issue, so replace it with clean, fresh gasoline. Another potential cause is a plugged vent in the gas cap; clear the vent to resolve this. Additionally, water or dirt in the fuel system can lead to erratic engine performance; run the engine until it stops from lack of fuel, then refill with fresh fuel. Finally, a blocked fuel line may be the cause.

      If your Craftsman Lawn Mower is vibrating excessively, first check if the cutting blade is loose or unbalanced. Tighten the blade and adapter, and balance the blade if necessary. A bent cutting blade can also cause excessive vibration, so replace the blade if it is bent.

    Why Craftsman 247.372370 will not mulch grass?
    • J
      Jeffrey YoungAug 21, 2025
      If your Craftsman Lawn Mower won't mulch grass effectively, avoid mowing when the grass is wet; wait until it's dry. If the grass is excessively high, mow once at a high cutting height, then mow again at the desired height, or make a narrower cutting path. Also, a dull blade can hinder mulching, so sharpen or replace it.
