Check your float setting first and gasket. Make sure the inlet needle is seating properly. If leak still persists, it most likely a warped casting. Take the carb off the manifold and disassemble the air horn and gasket where it mates to the carb body; Put the air horn back on the carb body and hold it up to a light. If you can see light coming through you have a warped casting. You might be able to get away with a little bit, but I would look for another carb. There is a temp fix that involves disassembling the carb completely, and making a jig to clamp the air horn and body and bake it in the oven. Someone will chime in on that.
