I thought it was the Rochester Bs that had the warped base problems
How do I know if it's a 2100 or 2101?
Yes, this carburetor does appear to be leaking from the area you describe. It isn't obviously warped but I haven't taken it apart and put it on glass. Is it possible that the gasket is just messed up rather than the body is warped?
If warped can it be repaired? Is that something a rebuilder would normally check?
