Can anyone explain to me how the fuel system on a bike bug works. I have an old one I bought years ago. I got it to run but It would not pump fuel. I think theres a problem with the way the gasket is on, or maybe something is missing. Where the lines goes in and out there is one gasket that has two holes in it. Tryed it all different ways. Just can't figure how it even supposed to work. With the engine cranking air pumps out of one hole under the gasket so i assume something is kinda working. I wanna try friction drive and this motor seems sound in every other aspect. I'm waiting for my NT carb. for my other bike so right now I have some time to play with something else
