  There are several possible reasons why your Craftsman Lawn Mower engine might fail to start: * The blade control may be disengaged. Ensure it is engaged. * The spark plug boot may be disconnected. Connect the wire to the spark plug boot. * The fuel tank may be empty or contain stale fuel. Refill the tank with clean, fresh gasoline. * The engine may not be primed (if equipped with a primer). Prime the engine as instructed in the operation section. * The spark plug may be faulty. Clean, adjust the gap, or replace it. * The engine may be flooded. Wait a few minutes before attempting to restart it. * The fuel line may be blocked. Contact your Sears Parts & Repair Center to have the fuel line cleaned.

  If your Craftsman Lawn Mower engine runs erratically, it could be due to: * A loose spark plug boot. Connect and tighten the spark plug boot. * Stale fuel. Replace with clean, fresh gasoline. * A plugged vent in the gas cap. Clear the vent. * Water or dirt in the fuel system. Run the engine until it stops from lack of fuel, then refill with fresh fuel. * A dirty air cleaner. Refer to the Air Cleaner section in Engine Maintenance. * A blocked fuel line. Contact your Sears Parts & Repair Center to have the fuel line cleaned.

Why won't my Craftsman 247.374900 mulch grass?

  Mrs. Jacqueline BrownAug 31, 2025
  If your Craftsman Lawn Mower won't mulch grass, it might be because: * The grass is wet. Avoid mowing when the grass is wet; wait until it dries. * 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. * The blade is dull. Sharpen or replace the blade.
