The Stovebolt Site Forums The Shop Area Engine Shop Rochester B carb gas leak

I just rebuilt the Rochester B carburetor on my 1952 Chevy 3100 with the 216 engine. But now gas is slowly seeping out of the two big screws that attach the throttle body to the underside of the carburetor. I tightened them up but it didn’t help. When I rebuilt the carburetor I replaced that gasket with the new one that came with the kit from Mike’s carburetors. I am sure I cleaned off those surfaces and made sure the were no burrs. What would cause this leak? It doesn’t look like gas is leaking from the gasket at the top of the carburetor and running down the outside.
