On a 72, the vacuum retard should disappear as soon as you open 
the throttle a bit. In your case you may not be opening it enough at 
the point where you see the "dead spot," but you should check to 
see that you ARE getting the proper timing response in this area. If 
you're not, you can't expect anything else to be working right, 
either.
