I seem to recall a post that said this hole was supposed to be open to the manifold ... anyone know anything about this? Thanks

Yes, there is a hole (for vacuum?) in the base of the carb that hole should match up with a hole/notch in the carburetor gasket that also lines up with a notch in the carburetor-to-intake spacer/insulator.
