Craftsman repair parts that you may need for your gas walk-behind lawn mower
Fuel filter. The fuel filter traps dirt and contaminants in the gasoline before the fuel enters the carburetor.
Gas tank cap. The gas tank cap covers the fuel tank and has a small vent in the cap that allows fuel to flow out of the tank to the carburetor.
Sparkplug. The sparkplug provides the ignition spark that lights the fuel inside the cylinder to drive the piston.
Flywheel key. The flywheel key mates the flywheel to the engine crankshaft.
How to fix your Craftsman gas walk-behind lawn mower when its engine runs rough
If your lawn mower cuts out, smokes, idles poorly, vibrates or runs erratically, it could need a good tune-up to replace the spark plug, oil and air filter. Or the problem could be with the lawn mower's fuel system. Rebuild or replace the carburetor if the engine isn't getting a good supply of fuel.
If the engine misfires, backfires, sputters or jerks the starter rope out of your hand when you try to start it, the flywheel key could be broken. A broken flywheel key disrupts the ignition timing because the magnets aren't passing the ignition coil in synchronization with piston movement. Replace the flywheel key if it's damaged or broken.
