[QUOTE="2smoke, post: 83772, member: 563"] Im liking your input Dan. There is only just one adjust screw on the carb and Im pretty sure that it is only just the mixture screw. When I messed with it, the further in you tightend it the higher the revs got untill you ran the screw all the way in, and the engine would die. So I backed it out about 1 1/2 turns or so started the bike again and slowly started backing the adjustment screw out till the idle came back down. But then when you would snap open the throttle it would (hesitate) bog and the revs would come up. Which tells me its to rich. So at my next opertunity Im going mess with choke. But its on a cable mounted to the handle bars, so Im unsure if that is adjustable. As Kyle mentioned I did mess with the throttle cable length but it really didnt do much. As for pictures. Its my niece's bike, so its stored at her dads house, but they do only live just down the street. So............. Im going to play with the bike first with the new info that I have. If I cannot get the idle adjusted it correctly I will be sure to bust out the camera and take some photo's of everything that I was able to find and mess with. [/QUOTE]
