So pulled the ole 1940 off and put a yf on the 200 tonight and though id go ahead and put the msd box that I picked up at a swap meet on. Its an old 5200 points box. Well what im wondering is should I reset my timing? Im not familiar with running one. And I guess next upgrade may be a blaster coil. What yall think? By the way si far the slight skip that used to be at idle is gone but I will.give that credit to the carter.
