Trouble Starting after sitting

This happened to me on my Impala (i know,not a Mopar) but the carb was leaking fuel and I couldnt find out where exactly.I even put a new gasket kit on it,and same thing.Then I noticed gas was leaking from the seam under the float bowl.I say clean the hell out of the outside of the carb and look everywhere for small cracks.I barely barely saw the crack on my Impalas Rochester.
