Kx 250f hanging idle issue.. so hey guys I just picked up a 2009 kx 250f and guy couldn’t get it running after he “cleaned” the carb. So I got the carb completely rebuild and had the bike fire up! Yay right? But here’s the issue, won’t start unless I full throttle it then let off once it starts but I have to keep it running. If I slowly give it throttle it hangs idle for a few seconds. And then it dies out. If I play with the idle screw and make it idle high it will but it pops here and there out of the exhaust.. not sure what to do if anyone can help that would be GREAT!
