the bike runs good but when I stop fuel leaks out the bottom drain on the carberator. the screw is tight. the needle valve looks to be perfect and I cleaned everything real good. as per the manual I bent the tab on the float. I tryed this several times and when I finally got the leaking to stop the bike ran terrible so I bent the tab on the float back to straignt and it runs fine but leaks fuel again. any ideas? the instructions in the manual are a bit hard to undertand when it says to line up the float and the neelde valve. I dont rally understand what that means.
