What to do if Craftsman 247.203724 Lawn Mower engine runs erratically?

  Terri KingAug 17, 2025
  If your Craftsman Lawn Mower engine is running erratically, it could be due to several reasons. First, check if the choke is activated and deactivate it. Next, ensure the spark plug wires are securely connected. A blocked fuel line or stale fuel could also be the culprit; in this case, replace the fuel line, fill the tank with clean, fresh gasoline, and replace the fuel filter. Additionally, check if the vent in the gas cap is plugged and clear it, or replace the cap if damaged. Water or dirt in the fuel system can also cause this issue, so drain the fuel tank and refill with clean, fresh gasoline. Lastly, a dirty air cleaner can lead to erratic engine performance, so replace the air cleaner paper element or clean the foam pre-cleaner if your mower is equipped with one.

  Vicki Sawyer DDSAug 21, 2025
  An uneven cut with your Craftsman Lawn Mower can be caused by several factors. First, the deck might not be leveled properly, so perform a side-to-side deck adjustment. A dull blade can also contribute to an uneven cut, so sharpen or replace the blade. Finally, check the tire pressure in all four tires, as uneven tire pressure can also cause this issue.

  If your Craftsman Lawn Mower engine idles rough, it could be due to a spark plug issue. The spark plug might be fouled, faulty, or have a gap that's too wide. Try replacing the spark plug and setting the correct gap. Another potential cause is a dirty air cleaner. In this case, replace the air cleaner element and/or clean the pre-cleaner.

Why Craftsman 247.203724 is not mulching grass?
- A
  alexanderhansenAug 28, 2025
  Your Craftsman Lawn Mower might not be mulching grass effectively because the engine speed is too low, so place the throttle in the FAST position. Avoid mulching when the grass is wet. 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 swath. A dull blade will also prevent effective mulching, so sharpen or replace the blade.
