They did, indeed feel stiff and winding seems normal. It is gear reduction winding on this type motor, not direct so winding is easy.

Does it seem to have good tension when you wind it? I don't know if this will help, but I would let it run down completely and then count the number of turns to get it fully wound. Then ask someone with a Credenza with a good 4 spring motor to do the same and compare the results I didn't see Georges sugestion. What was it?
