I have an old c50e motor that I've been running on the bench, been running it off a 6 volt coil that I rigged up from my one of my willys jeep spares. Runs great (a few leaks but nothing major) so I thought I'd get a more permanent coil solution, I got a chinese one online but it didn't last long so wondering if I bought a dud or are CDI coils (i assume that's what its for) are not meant to run with points ignition?
