XR100 Carb overflow

Recommended Posts

I am having a problem with my 1998 xr100 carb leaking gas out the overflow.

I have cleaned the carb/jets and the float/pin seems okay it shuts off flow good manually. It seems to run good, but when you stop it pours out the overflow. It does have a small crack in the outer rubber part of the intake

manifold, it didn't show to leak when I air tested it, could this be the problem?.

Thanks,

I'd assume your float is not moving up to the off position. Remove the carb and double check the float. Does it have fuel in it? If not turn the carb upside down so the float is in the up position, then put the float bowl on. I have had floats stick down because they catch on the bowl cover if it is put on while the float is over extended down.
