Nothing ground breaking here. The biggest revelation was that I really didn’t need a major overhaul but doing so was a great learning experience. I really did not have a complete handle on all the fine points and now I do. My 55 year old teflon shaft seals actually looked pretty good although I did replace them. Seeing how easily the choke linkage and fast idle screw can mess with the throttle plates was a biggee, These settings and getting all the other linkages in place so that the throttle plates and jets are in their home position is very fiddly and it took me a fair amount of time to get them right. I have the Haynes SU carb book and it was great, the nominal tuning positions were a great starting point as the car started up immediately with them in place.
So if anyone is contemplating this as a diy my advice is to go for it, questions/comments welcome.
