Well it looks like you were right.  It appears that my problem with
the 'governor', was in fact, a problem with the mounting of the pump.

The pump is mounted with 3 bolts up by the input shaft and one bolt
just below the 4 unions that deliver fuel to the 4 fuel lines.  This
last one was missing.  I must have forgotten to tighten it and it fell
out.  When I replaced it the problem with the funny acceleration

It looks like I have recovered from yet another brain-dead error.

At this point I have not figured out how allowing the pump to move
sightly can cause such a noticable problem.
