I'm just going to throw this out there because my brains starting to get fuzzy-er,, maybe someone else can straighten this idea out,,
If you're advancing it 45 degrees at the crank, that's going to be 27 1/2 at the cap , your rotor is half way to the next plug wire contact, so a stock ignition likely won't make the jump,, and with the old MSD system,, wouldn't you be hearing a tremendous snap as the spark jumped from rotor to cap,... hmmmm?
by the way,, I watched the video,, it sounds great, something is just wacky.. grant
Is the dizzy cap locator right, or is cap twisted somehow? or rotor locator broken, rotor twisted, rotor end contact bent??
