    Why Craftsman 247.397600 engine fails to start?
    • A
      andrew16Aug 13, 2025
      Your Craftsman Lawn Mower might fail to start due to several reasons: * The blade control might be disengaged, so engage the blade control. * The spark plug boot might be disconnected, so connect the wire to the spark boot. * The fuel tank might be empty or contain stale fuel, so fill the tank with clean, fresh gasoline. * The engine might not be primed (if equipped with a primer), so prime the engine as instructed in the Operation section. * The spark plug might be faulty, so clean, adjust the gap, or replace it. * The engine might be flooded, so wait a few minutes to restart. * The fuel line might be blocked, so contact your Sears Parts & Repair Center to have the fuel line cleaned.
