But if he has to spin it to start it, that would imply it's just a
starting capacitor. Can you hear an audible click as it picks up speed
and again just as it slows to a stop?
No, a split phase induction motor with an open or missing cap will not
start regardless of whether it is a start or run cap. Spinning by hand
will get it going (assuming minimal load).
An induction motor designed to have a run cap will still run without one
if started manually but won't have rated torque.
An induction motor designed to have a start cap will still run without
one if started manually and will have rated torque.
The main functional difference is that the start cap is not rated for
continuous operation and is removed from the circuit once the motor
reaches about 75 percent of operating speed.
