Setting points on a Sun machine does not require that a coil be used. The procedure is to first be sure the machine is calibrated, then block one set of points as the distributor is run, set the unblocked points, then unblock the points and set the dwell by the other point set to show the combination dwell. At our shop we calibrate lots of old Ford distributors on our Sun machines. The strobe feature is very useful to check for problems with shaft wear or other signs of instability such as point bounce due to weak point set springs. Checking he advance is useful to detect problems with the weight springs.
