geezer is right on the link.....I run 16 deg initial with 20 deg mechanical advance in the distributor for a total of 36 deg mechanical timing all inby 2500 rpm. At idle with 10 degrees of vacuum advance it idles at 26 degrees. Fires up at a touch of the key and shuts down without dieseling using the full manifold vacuum port on the carb.
This method works great just takes a bit of time and patience.
