I was having issues getting fuel to the carburetor so I installed a new pump. Now that I have fuel getting to the carburetor the bowl will not fill, the fuel just sits in the line. Do I need to rebuild the carburetor? I don't believe I have a fuel shut off solenoid because there's no wires going to the carburetor so that shouldn't be a issue. I do have rust hole in the fuel line coming from the pump to the carburetor so it could be a pressure issue. Anybody have any idea what's going on?
