Flathead ignition

Hey guys, my coil slipped down and is rubbing the fly wheel. What do I space it at? Brian, it’s a motor you built a very long time ago.

Probably what has happened is that the bearing and pocket have worn some and allow the flywheel to move up against the coil.
Set the coil air gap at a minimum of .016." I prefer to set the right leg a bit further away. It's not a big deal, just something I carried over from years of flathead small plate experience. Just be sure that the flywheel isn't rubbing any more -- you don't need the brakes on. :)

Thanks for the help guys, the error was self inflicted. Whooops. Brian is guessing you do not build them anymore by the sounds of it?

I still build them on a weekly basis. There has been no shortage of flathead work in our shop over the years. 31 years now and still building flatheads (from mild to wild.)

If you need ANYTHING, please don't hesitate to give us a call.
