Hello to all.....
I recently aquired my first spark engine (Madewell .49) at a swap meet and was happy that a Champion plug was included. I checked the plug with an ohmmeter without removing it and it seemed to be shorted (less than 1 ohm). When I removed it I was surprised to see a heater coil, no spark gap. Externally it looks like a spark plug, its marked "Champion Made In USA VG2". Just what have I got here, did Champion make glow plugs when they began to get popular or what? This engine is complete with timer/points so I'm a little confused.
THANKS
