Bingo Sir!..and same here..advance was so high at start/idle..it would wanna kick back and not start very easy at all. With one I thought my compression was causing detonation..but on a whim swapped back my stock CDI..and the problem went away. But still I have yet to find a performance CDI that actually had 'advanced timing'..just fixed timed ones..
