Jack,
If you have a timing light (hopefully a dial back to zero type) can you tell 
us the number of degrees of Total advance (with the vacuum advance 
disconnected) at idle (specify the RPM) & at some high RPM such as 3000, 3500 
or 4000?  
 
Also, please verify that the vacuum advance is functioning. I stick a plastic 
tube on the vacuum advance connection & suck. Watch to see if the points 
plate in the distributor rotates under a vacuum. 
Thanks,
Gary
