as far as i understand it, there is a mechanical advance to sort it for the correct revs, and a vacuum advance to sort the load (effectively throttle
position)
i havent bothered with the vacuum advance on mine cos i couldn't be arsed plumbing it into my new air filter.

Joel P is basically right, the vac advance does as it says on the tin, and advances the ign timing under high vacuum conditions, i.e. low throttle
overrun/cruise type conditions. You will lose fuel economy but performance will be fine in terms of power as then the throttle will be wide open and
there will be no vacuum so no vac advance anyway!
