done a few..
I've rebuilt all the ones I've owned,but that was quite some time ago--also done many Edelbrock Performers too,which are nearly identical to the AFB,(but not many parts interchange however)..
All mine needed were new accelerator pumps and a good cleaning,(one had a leaky float),since I bought them all used,either at swap meets,boneyards,or from someone elses vehicle when they decided to go to a Holley,etc..(and some of them regretted doing so,and called me up and asked me to sell them their old carb back!)..I also had two factory AFB's that came on my '66 Buick 401 motors..
I like these carbs a lot for street use--I've had them on everything from a 250 six cylinder to a 500 Caddy,and they deliver good performance,decent gas mileage,and are simple to fix ,but they also don't screw up or go out of tune very often..but I don't reccomend them for off roading,if you get the truck bouncing ,go up or down steep inclines,or off camber,they flood out easily..there are spring loaded needle valves that supposedly help this,also some other modifications--but a Q-jet is better stock than an AFB style carb will ever be in those conditions..on the street they are hard to beat..
