Furthermore at idle the vacuum advance is fully  advanced,  when 
you rev the engine the vacuum advance goes back to a  "retard""  original 
position as if there was no vacuum. What I have  done:
 
Harry gave pretty good advice. One way or another, you should have  No 
vacuum being applied at the advance unit at idle. First check the  carb tube you 
have connected to. (I hope that is the vertical  one.) If you are getting 
vacuum at the vertical tube at idle,  the throttle plate on that carb is too 
far open at idle. Have you  verified that you have no other idle leaks? Does 
the 1960 use a crossover  tube? Did you disconnect the throttle linkage 
when you balanced the carbs  after installation? If you don't, you will be 
chasing your tail trying to  adjust the idles.  The vacuum change you see is 
normal -if the vacuum is  incorrectly attached. There is a lot of "manifold" 
vacuum at idle, that drops  off quickly when you open the throttle plate. Be 
very careful with the  gaskets above and below the spacers, I try to avoid 
using them, but I deal  with late models, the 60 is probably different.  Let 
us know what  you find.
