But what vacuum advance does your car have? If you have the stock distributor, you probably actually have a vacuum RETARD, not and advance. I do not think there is a practical way to hook this to HS2s. Besides the vacuum retard does not contribute to power or fuel economy, only to reduced idle emissions. The most practical thing is to leave it unconnected and adjust the idle timing to -6 deg. or so.
If you have a different distributor with a real vacuum advance mechanism, many HS2s have a port on the front side of the front carb. There is a flat spot molded into the carb body at that location. But drilling the hole would be tricky, since it has to enter the carb body at a precise location quite close the the throttle valve.
