if you mean where is the tickover screw its on the side of the carb,lift up the seat and there will be a small panel in the seat bucket undo the screw and you will see the screw next to the throttle cable guide twist the throttle and you will see it move.DO NOT adjust the tickover with the throttle cable adjuster its not the way to do it and its dangerous as a tight cable can cause undue revs if jamming occurs the cable should have free play in it .
