All starter taken off and dropped at repair shop. Quick diagnosis before opening and disassembly by repairmen. He was able to turn the drive gear both directions by hand with no tools, while turning he was looking and the armature was stationary. Indicated something, possibly the woodruff key was sheared, will disassemble and repair cleaning and updating anything needed. This is why I was hearing the spinning sound and not having the motor turn over.
Will document the findings when complete.

Appreciate the tip for not using ether, I did get a small container to fill with gas and use instead.

Thanks all, bugnut
