My 97 KTM 250exc with Kehein carb starts and accelerates well but when the throttle is shut it idles like it is running out of fuel. A rolling idle. If I slow the engine with the kill button it will finally idle ok. Any ideas. Pilot jet or maybe a needle and seat kit? The engine has always run well and this problem has just started this fall and seems to have gotten progressively worse. Thanks
