    Carb Float height Adjustment help

    I have a Kawasaki KLT 185, Ive been having problems with the carb (I think, Its skipping) So I tore it apart and am going through it, The book says float height should be 33 mm.... How is this even possible? The highest it can go is about that height, The second photo is me holding the float all the way up....

    What should I set it at?

    I have zero experience with Kawasaki's, but there is an alternative method to use as a general rule if you don't have the specs handy. This also requires a carb with a float bowl drain on the bottom. If you connect a clear vinyl hose to the drain and run it up along the side of the carb, you can use it as a sight glass. Make sure your hose goes up a few inches past the float bowl. Open the carb drain and the fuel will rise up in the tube. I've read here and other places that a rule-of-thumb float level is to have the fuel level right at the seam between the float bowl and carb body.

    Of course, if you can figure out the measurement method like you are using, that is probably best. But in case you want another way, try the clear tube idea.

    I am assuming I can do with in a vise or something as long as fill the carb with fuel? Kawasaki made the carb annoying as heck to keep taking in and out...

    The key is to hold it at whatever level it would be at mounted in the machine. In other words, if it is at a slight angle in the machine, then try to match it as close as you can when holding it in the vice. Otherwise, I don't see any problem doing this remotely. Again though, this is just a fall-back plan when there isn't another way. Hopefully somebody with experience actually measuring the float height can chime in and answer your original question.

    I recall Mr. Sound was looking for parts for his and we concluded that it was basically the same carb as the Yamaha YTM 200.
