This indicates a rich fuel mixture; adjust the carburetor or check the air filter for blockages.
Oil fouling may suggest worn piston rings or valve seals; consult a professional mechanic for engine inspection.
Before installation, ensure the engine is completely cool to prevent thread damage in the cylinder head. Use a spark plug socket to avoid cracking the ceramic insulator. Always check the electrode gap against your engine manufacturer's specifications, as even pre-gapped plugs can be bumped during shipping. To care for your spark plug, avoid over-tightening; use a torque wrench to meet the manufacturer's recommended torque settings. Regularly inspect the spark plug during routine maintenance to check for carbon buildup, which can be cleaned with a specialized wire brush or replaced if the insulator appears discolored or worn.
