AMF Roadmaster Moped RMI01 Champion DJ8J spark plug. (AMF internal engine part 1.)

This is a used moped part from a 1978 AMF Roadmaster moped McCulloch 49cc engine. It is the used spark plug that was installed in the engine. I'm not sure if it is the exact spark specified or included by the manufacturer. Probably not very old, since its not rusted. Sold "as is".
