Russ,

This typically means that your idle mixture is on the rich side.  When you
pull the large vacuum line, you introduce more air into the intake stream,
which is just like opening the throttle slightly.  The fact that this extra
air leak isn't passing through the carb having more fuel added and still
the rpm increases, points to the overall mixture being too rich (with extra
unburned fuel available).  If your overall idle mixture was on the lean
side, pulling a large vacuum leak would usually cause a noticeable decrease
or roughening of the idle, as the leak causes the mixture to lean out even
more.  Make sense?

A rapidly fluctuating gauge could be indicative of a burned valve or
compression problem also.  Have you checked the compression lately?
