Thought I'd chime in my 2 cents worth. I was thinking that maybe the float is set too high. As long as it sits there, it wouldn't leak out. But vibrate it, cranking it over would cause that over-full bowl to slosh about and thus the leak even if the needle is seated. Similar to turning a push mower over on its side and gas pouring out the carburetor. Try setting the float a little lower down so it will cut off sooner. You'll still have lots of gas, but the bowl won't be so full. Hope this helps.
