" From: "Larry R. Daum" <mramc@xxxxxxxxxxx> " " " If you used " for example a new distributor gear with an old cam gear. Well they need to be " a match set, either original old and matched new. If you mixed and match that " could very well be the problem, if the gears were not a match set. " Seems a simple " thing but I'm told the gear need to be a set to work right for some " reason from the same " source. Matching manufacturer and hardness I suppose.
