When I advanced the timing to experiment with getting a smooth idle I knew I had gone "too far" when the engine would not turn over when attempting a re-start and would occasionally kick-back. I am confident that the present issue is a tired old starter motor and an engine that has compression for the first time in two decades.
Jim M. also asked about the PCV valve and its connection. At the moment I have a new-old-stock PCV valve. I never trusted the old one and bought this one to insure I was starting with a clean slate. It certainly would be easy to plug the manifold connection and see if this has any impact on the idle vacuum readings, but after last night I was able to get the engine to develop about 11" of vacuum. The pundits say that the S2 cam I am running will typically produce around 13" at idle so I am not that far off now.
Thanks for the continued suggestion. I plan to re-torque the head over the next few days and if the weather permits I will work on getting the carbs better dialed in to work with the rebuilt engine and new cam.

: Hi
: Not sure if you are describing
: "hard cranking" with ADVANCED
: TIMING (draws alots of amps) or you
: feel the motor is tight! (you would
: have felt this on assembly)
: THE OTHER thing - you may have done
: (that would cause stalling when
: driving) is to use the wrong MK1 fuel
: pump !!! Please talk to us as to what
: was used ( and or ask what to look for
: in the difference) Mark
