Rochester B - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I recently rebuilt the Rochester B in my '62 Stepside (235) but it's still giving me trouble. At first it seemed to be "leaking" by fuel spilling over from the top. I assumed the float had dropped or some such so I rebuilt it with a kit from Mike's Carburetor (kit seemed good quality).

It runs great (better than before) but now it is leaking between the air horn and the bowl. From everything I've read I'm thinking one or both of the parts are warped. Some people have told me to double the gasket and see if that works. I'm also wondering if I can just put a little permatex or indian head stuff on the gasket and see if that makes a good seal.

Any advice or opinions?
