    Why my Craftsman Lawn Mower engine fails to start?
    • M
      Megan HoganJul 31, 2025
      If your Craftsman Lawn Mower engine won't start, possible causes include: the PTO/Blade Engage knob is engaged (place it in the disengaged/OFF position), the parking brake isn't engaged (engage it), the spark plug wire is disconnected (connect it), the throttle control lever isn't in the correct starting position (place the Throttle lever to FAST position), the fuel tank is empty or the fuel is stale (fill the tank with clean, fresh gas that is less than 30 days old), the fuel line or fuel filter is blocked (replace the fuel line; replace the fuel filter), the spark plug is faulty (clean, adjust the gap, or replace the plug), the engine is flooded (crank the engine with the throttle in FAST position), or a fuse is blown (replace the fuse).

    How to fix an uneven cut with my Craftsman Lawn Mower?

      Jason ColeAug 5, 2025
      If your Craftsman Lawn Mower is giving an uneven cut, it may be because the deck is not leveled properly (perform a side-to-side deck adjustment), the blade is dull (sharpen or replace the blade), or the tire pressure is uneven (check the tire pressure in all four tires).

    What to do if my Craftsman 247.20400 Lawn Mower engine runs erratically?
    • H
      Hailey SmithAug 8, 2025
      If your Craftsman Lawn Mower engine runs erratically, it might be due to several reasons: the riding mower running with the choke activated (check that the electric choke is working), a loose spark plug wire (connect and tighten it), a blocked fuel line or stale fuel (replace the fuel line; fill the tank with clean, fresh gasoline and replace the fuel filter), a plugged vent in the gas cap (clear the vent or replace the cap if damaged), water or dirt in the fuel system (drain the fuel tank and refill with clean, fresh gasoline), or a dirty air cleaner (clean or replace the air cleaner paper element or clean the foam pre-cleaner).

    Why is my Craftsman 247.20400 engine overheating?
    • R
      Ryan MatthewsAug 12, 2025
      If your Craftsman Lawn Mower engine overheats, it could be due to: low engine oil level (fill the engine with the proper amount and type of oil) or restricted airflow (clean grass clippings and debris from around the engine’s cooling fins and blower housing).

    Why does my Craftsman Lawn Mower have excessive vibration?
    • R
      Ruth Brown MDAug 17, 2025
      If your Craftsman Lawn Mower has excessive vibration, it could be because the cutting blades are loose or unbalanced (tighten the blade and spindle; balance the blade) or the cutting blade is damaged, dull, or bent (replace the blade).

    • K
      Kevin PetersenAug 22, 2025
      If your Craftsman Lawn Mower engine hesitates at high RPMs, it might be because the spark plug gap is set too close (remove the spark plug and adjust the gap).

    • C
      Christopher AndersonAug 26, 2025
      If your Craftsman Lawn Mower engine idles poorly, it could be due to a fouled spark plug (replace spark plug and adjust gap) or a dirty air cleaner (clean or replace air cleaner element and/or clean pre-cleaner).
