Where is the idle screw for a 1988 rm 80?

well it depends on whatcarberator you have on it if yours have the choke on the side that you pull up then you idle it by turning the choke after you pull it up if your choke pulls out from the side then look on the right side of the carb and there will be a screw on the right side turn it too the right to get it to idle hope i helped
