I recently purchased a 2005 kawasaki prairie 360 and it won't Idle unless I'm pressing the accelerator or have the choke on. It won't even start up with out the choke on. I already ran some carb cleaner through it and took it apart and sprayed the jets with carb cleaner. I also tried adjusting the idle speed screw to see if that would help it idle but that didn't help either.

 

are u sure you turned the screw the right way? I know on my 400 the vibration of riding is constantly moving it.. Try pulling the bowl of bottom of carb and cleaning it out their may be some crap in it.. If i remember correctly its just 1 screw holding it in
