I used a dubro fuel filler,kept things simple on this one, yes I know they can and do go bad but there a easy fix, I have a rebuild kit in my fight box if I need it. Thats the only one I have all the rest are 3 line set ups. Must have thought I needed it for some reason, but what *L*
Oh unless you plug the hole in the muffler the fuel will never flood the engine when filling like is described above.
