Recently baught a 03 250 ex did a valve job and cleaned everything up real good and she now runs like a raped ape rear end rebuild also, when accelerating or reving the throttle will stick not all the way open but sound like it’s idling much higher then will come back down to normal or if you turn key off on real quick it’ll cause it to go back down too is the carb sticking or clogged? Ran Seafoam, injector cleaner and another cleaning fuel additive and it ran a lot better becouse it sat for awhile but now this has come up thanks for any and all help:)
