Jon (Carb King) makes me look like a rank amateur where carburetors are concerned. Despite his (and my) distaste concerning Rochester carbs, he makes the best rebuilding kits out there for these carbs, and he has an impressive stock of original equipment parts, not the "one size fits none" generic kits the local parts stores stock. Since the carb I gave you is missing the ID tag, there will be some guesswork concerning the exact application, but it came off an engine for a 1953 truck 216. Maybe next time we meet we can find a place that actually serves coffee!
