Now maybe I have the final solution. When a solution happens to come to mind can make so much difference in the time it takes to solve a problem !!! confused clapping

I noticed that one side of the frame is not straight on the bottom.

Then I noticed that the side has a slight wobble. When it is tight on top the insides of the frames are 3/4 apart. I noticed that when I held them apart, the separation was 13/16. Looking at the first and third photos you can see the end of the frame spacer. In the second it is held together tightly.

So I tried rotating the wheels in those two situations. When I held the frame together, all turned freely. When I released it the motor jammed. I seems that the minor difference in the angle of the bearings is causing the armature to bind. Tomorrow I will test the motor with a clamp holding the top of the frame together.
