re: Motorized Bicycle Take a Tip...Leave a Tip
I have seen pictures of early auto engines with just a bare clip from magneto wire holding onto the center electrode of the spark plug. There was nothing OSHA-compliant about them at all. But they worked.
By the way.... How does a spark plug cap simply go flying off? Maybe I need to use a nylon tie-wrap to keep mine in place? (I hope not!)
