I assume you used new gaskets and one between the intake and TP and TP and carb? Any chance the edge on the TP got bent at all and is causing and indentation into the gasket and a leak? I also assume that none of the vacuum port nipples came off in the process? Might double check that. Uh, ask me how I know about that last one.
