<VV> Vacuum advance

[Richard]

I enjoyed driving my 66 convertible to town, and no farther. My fears were realized when all of a sudden it started sputtering at high rpm (power glide). I fad Dave Sigler rebuild the carbs, so c I eliminated that as a problem (the guy us very talented). Now, when I take off the vacuum hose off the distributor, it rubs better at high rpm.  Even though I can see the vacuum advance moving back and forth as the rpm changes, the engine still runs better with the horse disconnected.  Bad points? Bad vacuum advance? Bad timing?
