Hi Larry, Well, I guess if there is one lesson to be learned from all this mess.In the case of a ram car that pops back thru the carbs, the problem is not necessarily carburetor related. All my "gut feeling" and past experience with cars seemed to indicate that the popping was due to improper float level in the carbs. Indeed, I did drive this car to my carburetor repair shop, and test drove it, with the shop owner in the car. He heard the popping and also, immediately, concurred that this was a carb problem ! He indicated that he thought it was a lean condition occuring on turns . We played with the carbs for quite awhile until we both ran out of time and got nowhere. Couldn't find anything wrong with the carbs anyway - took the tops off, float level was to spec ! Yes, if Don Verity finds a specific problem with the distributor, we will share these findings with the list ! I still can't for the life of me comprehend how left turns could affect a distributor to the point that this one was affected... it defies my logic... but, so be it, the problem is solved. It was an immediate fix, the problem was constantly present before the distributor swap and disappeared completely with another distributor installed ! I will add this : it really helped, in my case, to have spare carbs and distributors on hand to swap out... if I didn't have the spare carbs, I'd probably still be chasing a carburetor issue ! John
