Dear friends, Thank you so much for all your help!  It did occur to
me that the leather nuts were faulty and -- come to find out -- they
were!  I replaced them and also found that the governor was not
properly "zero-ed out".

I fixed this adjustment, and now the system is much more responsive, but
it still does not play like it should.  More notes have started leaking
as the tubing cracks very easily, so I believe that the valves in the
stack are leaking so much that it is bringing down the system.

And I thought this would be an easy project piano!
