The only difference that I can find documented is that apparently "start"
caps are not rated for continuous duty, and "run" caps are.

So, as I understand it, the point that Jay made essentially seems to boil
down to the question of whether a "start" capacitor used as a replacement
would hold up in the operating environment of the TU56.

Not knowing anything about the failure modes of motor capacitors, I have no
idea.
