If the spark plug is dirty clean it with a wire brush and check the electrode gap. Readjust if necessary. The correct gap is (020” (0.50mm)

The spark plug should be replaced after 40 hours of operation or earlier if the electrode is badly corroded.

Always use the recommended spark plug type, Using the wrong spark plug can severely damage the piston and cylinder. (Champion RCJ7Y).
