    Why won't my Craftsman 247.397900 engine start?
    • A
      Angelica WilliamsAug 14, 2025
      If your Craftsman Lawn Mower engine won't start, there are several potential causes. First, check if the spark plug boot is disconnected and connect it. Ensure the fuel tank isn't empty or contains stale fuel; if so, fill it with fresh gasoline. If your mower has a primer, make sure you've primed the engine as instructed. Also, the spark plug might be faulty, requiring cleaning, gap adjustment, or replacement. If the engine is flooded, wait a few minutes before attempting to restart it. Finally, a blocked fuel line could be the culprit, in which case you should contact your Sears Parts & Repair Center to have it cleaned.

    What to do if Craftsman 247.397900 will not self propel?

      Dr. Stephanie GalvanAug 17, 2025
      If your Craftsman Lawn Mower is not self-propelled, check the belt to ensure it is properly installed on the pulley and moving correctly. Also, debris clogging the drive operation can be a factor; stop the engine, disconnect the spark plug boot, and clean out any debris. Finally, inspect the belt for damage or wear, and if necessary, see your Sears Parts & Repair Center to have the belt replaced.

    Why does my Craftsman 247.397900 engine run erratic?
    • B
      Brandi RobinsonAug 25, 2025
      If your Craftsman Lawn Mower engine is running erratically, start by checking the spark plug boot and ensure it is connected and tightened. Stale fuel can also cause this issue, so replace it with clean, fresh gasoline. Another possible cause is a plugged vent in the gas cap, which needs to be cleared. Water or dirt in the fuel system can also lead to erratic running; in this case, run the engine until it stops from lack of fuel, then refill with fresh fuel. Finally, a blocked fuel line could be the cause, and you should contact your Sears Parts & Repair Center to have it cleaned.

    Why Craftsman Lawn Mower will not mulch grass?
    • C
      coryhahnAug 27, 2025
      If your Craftsman Lawn Mower isn't mulching grass effectively, it might be due to several reasons. Avoid mowing when the grass is wet; wait until it's dry. If the grass is excessively high, mow it once at a higher cutting height, then mow again at the desired height, or reduce the cutting path width. Also, a dull blade can hinder mulching, so sharpen or replace it.

    Why is my Craftsman 247.397900 experiencing excessive vibration?
    • R
      rowlandluisAug 31, 2025
      If your Craftsman Lawn Mower is vibrating excessively, it could be due to a loose or unbalanced cutting blade; ensure the blade is tightened and balanced. Alternatively, the cutting blade might be bent or damaged, requiring replacement.

    • T
      Tammy GarciaSep 3, 2025
      If your Craftsman Lawn Mower is overheating, check the engine oil level and fill the crankcase with the proper oil if it's low. Also, ensure that the airflow around the engine isn't restricted by cleaning the area around and on top of the engine.

    Why does my Craftsman 247.397900 idle poorly?
    • P
      Paul BeckSep 7, 2025
      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 or replace the spark plug.

    Why does my Craftsman 247.397900 Lawn Mower have a high pullback effort?
    • C
      Carolyn DavisSep 10, 2025
      If your Craftsman Lawn Mower has a high pullback effort, allow the unit to roll forward slightly without the drive lever(s) engaged before pulling backwards. This is because you are pulling the mower backwards before the transmission disengages.
