My plugs are gapped to .025" all the way around.  The condensor and points
are Bosch.  Is the condensor also referred to as a capacitor?  If not, let
me know where to look for it and I will check it out.

The motor is a bit tight as it is a fresh rebuild (it can be easily
turned by hand), but each time before I attempt to crank the
engine, I remove the plugs to build oil pressure.  It does turn merrily
over under the power of the battery from my truck (so I know it's a fresh
one).
