2000 Prairie 300 4X4 Carb Problems

Sounds like your float valve is due for replacement, it could also be a bad float that has filled with gasoline. Either way the carb needs to be disassembled and inspected. You can go to Kawasaki.com and follow the links to the parts diagrams, select your model, and look at exactly how the carb is put together.

Once the carb is apart, if the float is good (and they usually are), order the float valve kit. The parts can be ordered from the sponsors's website, above. They are inexpensive and very easy for anyone with average skills to install.

THANK YOU, I'll order it tomorrow...

Went to the local dealer and he thought the lower end of the carb probably needed cleaning and talked me out of the float valve rebuild kit. I just finished putting the bike back together (carb was spotless) and still have gas flowing right through the carb into the overflow.

Once I turn the petcock on the gas fills the carb and pours out the overflow.

Do you still think the float kit will solve the problem?

Thanks,

Some of these do not have replaceable seats for the fuel float needle, and if that gets dinged or corroded it is time for a new carb. But, before I made that call I would check the float and the needle, paying particular attention to the part #16044-007, which is the float to needle clamp, to make sure it is properly installed.

Also, check the float to be sure it is not partially filled with fuel or sinks in fuel. Then make sure the needle tip is in good shape, no worn ring in the flexible tip, and that there is no fibers from a rag sticking in the seat and holding the needle open.

If the needle seats properly, and the float is adjusted, there is no way gasoline will pour out of these carbs, unless there is damage to the body itself and that would be an obvious crack or hole where something was removed.

Thanks RCW, it's great to have someone with your expertise who is actually willing to share it.

I'll let you know how I make out.
