Remanufactured Carbs

The story on rebuilds is that all the bases get removed and thrown together, all the bowls, power valves, horns, etc go into the same hopper media cleaner and then get put back together. With modern manufacturing processes going back the Henry Fords assembly line, all these pieces should be the same. Yeah....also some parts come with a teflon cladding/coating from the factory (TQ throttle shafts, choke plates, etc) and when they get bead blasted clean, this coating comes off. Now if they put it back on (Holley does in their TQ rebuilds) is up to the rebuild plant. So your in essence getting a very clean carb made with parts from 30 carbs, but all the specs are correct. I dont know. I never bought a rebuild so I have no experience on them but the OEM NOS one I bought for my truck started on the first crank and idled dead on at 650 RPM just like the manual said it was supposed to. Trouble with a 1920 rebuild is the bowl cover, most are already bent at the ears from years of cranking them down and some reportedly wont even seal.
