Default 250EX throttle sticking

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 itís idling much higher then will come back down to normal or if you turn key off on real quick itíll 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

I have had a sticky valve do that before if your talking about a high idle. Have you messed with the fuel air mixture screw?
