^^^^That's not how it works. When a camshaft is "large" you can't get it to run smooth enough with any amount of initial timing over a certain amount-lets say 20-22 intial. This is due to the overlap. You need to recurve your distributor and give it what it wants to run the most efficiently (ie. smoothly) You may want 20 degrees initital and only another 14-16 "in the plate" and then we get into the vacuum pot travel and rate. Fix the timing before you touch the carb-You'll never get the carb right without the timing right first. J.Rob
