Spark Plug Nut1. Spark Plugs

Spark Plugs are the #1 selling part on a moped. It’s good to have a spare. Spark plugs under normal conditions last for thousands of miles. But can only last 1 mile in a “sick” engine, if the insulator becomes fouled, or coated with semi-conductive carbon (black instead of brown or white). Once the white porcelain insulator becomes fouled, the plug no longer functions. Read about cleaning, gapping, and “reading” spark plugs in the Service Department.  At right, spark plugs are shown with and without the screw-on nut. Some spark plug caps require the nut to be on, while other spark plug caps need it to be left off.
