You can do it one of three ways. With a vacuum gage for the highest vacuum, with a tach for the highest RPM, or just by ear for the best running. Of course if the speed goes up higher than desired for idle, you need to turn the speed screw by the throttle lever to get the desired idle speed.
If an automatic trans, it's usually best to adjust it with the car in gear.
