Loose the retard vacuum side. Set the base timeing without the vacuum hooked up on the advance side. Then check for total advance with it STILL disconnected. When your done, hook up the advance side again.
Vacuum advance is not present under full throttle (or deep throttle) conditions. It is for "crusing" down the highway when the engine can use a rather LARGE amount of additional advance for fuel economy reasons more than anything else.
