I just realized, stupid me for forgetting, but the old Evo 58 engine uses a dual magnet sensor setup for firing the spark plugs. I think one magnet is north pole oriented and the other magnet is south pole oriented. Anyway that explains why it had to have a complete rotation of the crank to get a spark whereas other brand CDI's only needed one magnet. Thus just waving the sensor past a magnet back and forth won't trigger a spark like it does with a different brand CDI unit.
