'99 KX250......idle issues

Well, people will tell you that 2 strokes aren't supposed to idle..... but all of mine do ! My 03 kx250 got to where it didn't want to idle and when I'd crank it up it would rev really high and sputter back down till it finally would die. I cleaned the carb (concentrating on pilot jet) and check the seating of your float valve cause mine had a slight bend in the pin that holds it in place keeping it from seating properly. My kx now starts every first kick and idles smooth as silk.......and all day till it runs out of gas if I want it to. Good luck !
