Steve,

Let me get this straight: The motor spins by hand? I would check the brush
continuity. Just like a car starter that has sat around, the brushes may 
need
to be jarred loose with a not so gentle tap of a hammer on the motor case.
(We've all had a car at one time with that problem) This is assuming that 
you
get no continuity reading thru them. (remove one of the 2 large wires and 
test
accross both terminals). Hell, there might not be any brushes, but I am 
betting
there are and they are stuck or insulated from the comutator with old 
glazing.
Worth a try as it might just be a little "glazing" on the armature thats'
holding you back from that first ride!

Let us know,
Jim
