Bob, After I spun it power head with a drill for a while, it loosened up some.
I added a leather seal above the upper main bearing (where there
was no seal before) and it was snug as well.
The lower unit kept the original brass bushings, but I replaced
the crumbling cork seals there with leather ones. The lower
unit seems a little "stiff" as well, and when I got it attached
to the power head I was afraid it was going to be a problem.
But my fears eased when I put the flywheel on and spun it by
hand, it seemed decent. Next day I attached the cylinder and
piston, and the flywheel "rebounds" backward under compression
while spinning the flywheel by hand, so I think I’m okay!
Prepare to be boarded!
