gas running out carb overflow

[HONDA_ATC_FREAK]

When I turn my gas on will run out the overflow. I have taken it apart several times and cleaned it several times and nothing changes It just started doing this. What could be causing this theres nothing holding the float up it moves freely. :confused: Its a 30mm keihin on a 83 250r.

I think that the needle and seat have something wrong with them. Especially since it happened all of a sudden. I know you said you had it apart but it looks like it will be coming apart again. I run a cut off Q-tip in a drill with carb cleaner on it in and out of my seats. I find this polishes the brass nicely.

Is the seat what the needle slides in and out of in the main body of the carb?

In this pic, the float valve (# 2) gets pushed up into the inlet by the float to stop the flow of gas into the bowl. If the valve is worn or isn't getting pushed up far enough by the float, you will get overflow like you are experiencing.

On carbs with a metal tab where the valve attaches to the float, you can bend the tab up a bit to push this valve up more when the float rises, or you can try replacing the valve if the float is completely plastic. I've had success with both

I will try bending the tab SLIGHTLY:D and see if that cures the problem

I found the problem it was a ring of rubber from the fuel line I just put on, it came in through the fuel line and set right there in the float valve sits. It held it from closing just a hair. I couldn't see it cause it was dark but when I blew air through the fuel inlet side if popped out.
