Commonly replaced Craftsman lawn and garden equipment engine parts

Routine maintenance and wear-and-tear often lead to part replacements in Craftsman lawn and garden equipment engines. The air filter is one of the most frequently replaced parts—clogged filters restrict airflow and reduce engine efficiency. Spark plugs also wear out over time, causing starting issues and misfires if not replaced regularly.

The carburetor is another common replacement, especially when old fuel gums up the internal jets. Fuel lines can crack or degrade, leading to leaks or fuel delivery problems. Gaskets, including the head gasket and sump gasket, may eventually fail and need replacement to prevent oil or compression leaks. Replacing these parts as needed helps extend the life of your engine and keep it running at peak performance.

What to do when your Craftsman lawn and garden equipment engine leaks gas or oil

Leaks in your Craftsman lawn and garden equipment engine can reduce performance and damage nearby components. Start by checking the dipstick. If the crankcase is overfilled, drain oil until it reaches the proper level. Excess oil can cause pressure buildup that forces oil past gaskets and seals.

If oil continues to leak, inspect the head gasket and sump gasket for cracks or wear. Replacing damaged gaskets helps prevent ongoing leaks. When gasoline stains appear beneath the equipment, trace the fuel line to find the source of the leak. A leaking carburetor is a common cause. Rebuild or replace the carburetor if necessary. Also check the fuel pump for cracks or deterioration and replace it if damaged.

Troubleshooting your Craftsman lawn and garden equipment engine when it won't stay running

If your Craftsman lawn and garden equipment engine starts but stalls during use, the issue often lies in the fuel system. A clogged or dirty carburetor can restrict fuel flow and disrupt combustion. Clean the carburetor thoroughly or replace it if cleaning doesn’t solve the problem.

Also check the gas cap. If the vent is blocked, it can create a vacuum in the fuel tank and stop fuel from reaching the engine. Clearing the vent may restore normal operation. Performing a full engine tune-up—including replacing the air filter, spark plug and fuel filter—can also improve reliability and help the engine maintain power under load.
