I've been told by three people that I need a vaccuum advance in my distributer that connects to my carb. From what they said it all makes sense except there never was a vaccuum advance. No extra holes in the carb and no extra holes in the distributer. Did they even have a vaccuum advance in the distributers with points? what's a reasonable substitute if they didn't?
What year and make of engine ?
Some just used a mechanical advance inside the distributor. That is usually a set of spring loaded weights that move by centripetal force.
Vacuum advances are common for emissions purposes and are usually mated to a mechanical advance as well.

Should have a vacuum advance from the factory. Without it the symptom is momentary hesitation at throttle tip-in
