(0.76 mm)The correct spark plug to use is a Champion RC 14YC.Note: The spark plug usually lasts a long time; however,the plug should be removed and checked whenever theengine malfunctions.1. Clean the area around the spark plugs so foreignmatter cannot fall into the cylinder when the sparkplug is removed.2. Pull the spark plug wires off of the spark plugs andremove the plugs from the cylinder head.3. Check the condition of the side electrode, centerelectrode, and center electrode insulator to ensurethat there is no damage.Important: Replace a cracked, fouled, dirty, orotherwise malfunctioning spark plug.
