I almost have my car running right but with some small problems. I have no real experience with carbs and thought some of you 1st gen people would be able help. When i go full throttle it leans out pretty bad and then picks back up. I am thinking it might be a vaccume leak but i cant find one.What else could it be? Also would any of you have any tricks for tuning a holley for a 13b? The only one i heard have heard blocking off the powervalve
