hi how much centfifugal advance does the msd pro billet dissy have straight out of box ?
thanks

What color bushing is in it? There will be a chart on the box and in the instructions to tell you what advance the different color bushings offer.
This is the case with my #85551.

if you got directions with it, read em. If you didn't, downlaod them from msd and read them. Setting the advance amount and rate is a featured item. I don't remember which bushing was on it, except it was not the black one, and the springs were the stiffest in the set.
