??SO?? RECURVE IT. Crackedback and others have posted a chart that "someone made" showing approximate slot lengths / degrees advance
FBO makes a kit which several on here have bought with an "advance limiter plate" which makes DIY "no special tools" recurves easy.
Many current AFTERMARKET distributors are less than ideal advance curves, in fact a couple of people market shorter curve limiter bushings for MSD BECAUSE MSD DOES NOT PHECKING OFF THEM THEMSELVES
