Hey Jason, yes the vacuum advance should hold vacuum so it must have a hole in the diaphragm, it would be nice if you could get it separately but Honda does a lot of things that way, it is because that's how it was made to be assembled on the bike( or car)when it was built. There isn't much vacuum from the carb and it only has vacuum when you open the throttle.
My 83 had a problem like that with the self cancel and I found the arm on the steering sensor on the bottom of the steering stem was disconnected.

Bright lights, protective gear and paying attention saves lives. Loud pipes just annoy the people behind you.
