Kawasaki F11 250B is running too rich cuts out from half to full throttle....

Question

i know its running too rich but cant seem to adjust it out...if i leave the tank to the on position overnight the breather tube gets flooded with gas and i must pull start it to clear it out...cant find a rebuild kit so i dont really know what to do!!! PLZ HELP!!!!!!!!!!!

Answer 1

Sounds like the floats are set too high or the float valve is leaking.  In addition, the too rich from half to full throttle sounds like either a dirty, plugged air filter or too large a main jet.

Answer 2

Here's a carb kit for you.

The flooding  & rich running are more likely both rooted in same cause>>>bad float valve
