If you have checked the float height and it seems alright and the tip of the float seat needle and it isn't damaged, check the float needle valve by putting your carb back on the bike with the bowl off. Hold the float arms up and turn on the gas. If it looks like the float arms should be closing the needle into the seat and gas keeps pouring through anyway, you could have a bad o ring on the needle valve seat assembly. If so, the needle tip won't shut the gasoline off, because it is flowing around the outside perimeter of the seat itself. :nod:
