Wow that cleaned up nice. So that poor machine sat unused all these years because of a capacitor? Simply fix and off it goes. How nice is that.

It was mostly gridlocked in my garage.It's amazing how appliance hoarding can fill up space

great to hear that a machine after sitting for so long and needing only a capacitor replaced was able to come back to life and run. Would have been great if a video had been shot of it going off on it's "maiden" return to the living.
Would have been nice to enjoy the excitement.
Anyhow, wishing you all the best with your new toy and may it bring you many years of fun and service!

Capacitor?
Please forgive my ignorance, again. What does the capacitor do?

The capacitor is like a battery, it's stores an extra charge of electricity to give the motor extra power for starting to turn with a heavy load. There are two sets of copper windings in washer motors, start and run. When the motor first starts power is sent to both the start and run windings. When the motor nears full speed a centrifugal switch cuts out the start winding and the motor just uses the run winding. The capacitor is wired into the start winding.

Capacitor
Is the capacitor the problem when a Frigidaire begins the spin cycle and then stops after a few seconds?

I would like to add to Uni's description a bit.
When you have a 3-phase electric motor, each phase is off the previous one by 120 degrees, so all 3 phases make 360 degrees. Each winding is a bit off the other, so it's as if the electric field is rotating around the stator, which then makes the rotor follow it.
A single phase motor will show something similar, but the field only "rotates" by 180 degrees, which makes it hard to start the whole thing -- one it's already started, it goes just fine.
One of the ways to help it start is, like Uni said, to have a run winding and a start winding. When you put a capacitor and a winding like that in series the field shifts 90 degrees in comparison with the main (run) winding. That makes it simple, because now the rotor sees a rotating field of 90 degrees all around and the current induced in the rotor by the rotation field makes it easy to start. Once it's working, even if you cut the start winding out, the current induced in the rotor is always a few degrees behind, and that is enough to keep it going.
This is a very simplified explanation -- electrical engineers will complain about several details, but it's enough to get the idea. More info in the wikipedia link below.
