I have a late model (11/1969) CT 90 with the "2 bolt" carb. I see 2 brass screws on the left side of the carb. One is right next to the high altitude pull-out knob, and the other one is down lower on the carb body. Which one is the idle speed adjustment, and which one is the air mixture screw? On the idle speed adjustment screw, turning which ways lowers or raises the idle rpm?
Thank you for any help,
Michael
