The easiest way is to hook up a vacuum gauge to the manifold vacuum port and adjust the fuel air mixture to get the highest and steadiest reading. Then use the idle speed screw to set the idle around 450-550 rpm.
Vacuum gauges can be had fairly cheap from Harbor Freight and/or other tool-centric shoops as well as FLAPS.
