I've got gas coming out of a hole in the top section of the carburetor. If you take off the tope and expose the throttle cable assembley, and look down in the carburetor, you see a large opening and a small opening. The hold in the side of the carburetor goes into the small opening/chamber. The Key West starts fine but gas starts pumping out of that small hole. If put my fingure over the small hole and try to block the gas from coming out, the engine idles better. Any ideas/suggestions please? Thank you.
