Carb Newbie...

hey when i bought my bike the guy messed with a white plastic knob under the carb and small screw facing the shifter side of the motor on the very bottom of the bowl. I (obviously) know nothing about adjusting the carb but my idle is a little too fast. I tried turning the white plastic knob but it doesnt want to turn. Question is is that white knob the idle adjustment or am i not messing with the right thing... sorry for the probably obvious question but i cant quite find what im looking for using search:confused:

I hope you get your answer- I am dealing with lean running popping on deceleration and I turned that knob on the carb and it has improved my lean situation greatly but didn't really raise idle like I thought it would.

white nob will not fix a lean condition, has nothing to do with mixture..it adjusts the throttle resting position.. it should turn, clockwise to idle up, counter clock wise to idle down.

+1 :thumbsup: Also adjust it when the motor is warmed up.

when i try to turn the white knob either direction it wont turn it it kinda just bends side to side is it supposed to turn pretty hard?

it should turn with only a little resistence,,unless yours is seized, rusty,old 01 probably,etc..might want to try some wd40 or the like with the extension tube thingy, and spray it from the other side, give it a light tap...
