Show us some odd ignitions from the past
Wasn’t that Magspark coil made only for a magneto system Mallory made back in the late 60’s or early 70’s? IIRC it was somehow two separate ignition systems and you fired the engine on what was a basically a battery fired system, then you flipped a switch and that made it run on the magneto?
IIRC they made that system for engines with conventional starters. They didn’t spin the engine fast enough with a conventional starter to get the engine reliably lit.
Pretty sure that’s how it worked, or close to that.
