#63607 motor for Craftsman RAS #113.19770 buzzes, and jerks as if trying to start turning when i turn it on power. But when I give it a spin by hand it starts and runs, and the clutch opens to disconnect the capacitor. This is after I replaced the original equipment capacitor and blew all dust out with compressed air. Is it likely to be the bearings? Or, is there a component in the starter circuit that would prevent the capacitor from even kicking it when power is turned on? All suggestions welcome!

I'm sorry I can't help myself. But I would expect to find some ideas at

Table Saw went bad I could feel the blade jerk when turning it by hand.
However, the saw did start on its own and appeared to run fine. Try
turning the blade by hand to see how smooth it is.
Once in a very great while, it would hum and not start. A retry or a sharp
whack on the motor with a mallet would start it. It hasn't done that in more
years than I can remember.
Try blowing the dust out again. Maybe you moved something to a spot that's
causing a bad connection. It can't hurt.

Emerson has no listings for replacement motors for that model.

Probably it, but my table saw motor is from the early 50's. When it did

this 45 years ago, thinking I don't know jack about electric motors, I
took it to a motor repair shop and for $100 they fixed it. Few years
later it did it again, so I took the motor apart and sawdust was
clogging the switch area. Cleaned it out and worked good as new. The
motor had/has opened vents that lets in sawdust by the pound. I put a
nylon stocking over the ports and it took 35 years for it to happen
again, and I fixed it the same way, and it still works like new.
Hopefully his motor is totally enclosed, unlike mine, and it's just the
switch. I fixed a lot of old washing machine switches just by
cleaning/tinkering with the switch. _-

I think your clutch friction material is glazed and not transmitting rotation properly. Try lightly sanding the clutch friction material with a very fine sandpaper just to remove the glaze on the friction material (return material to near original friction coefficient). You don't need to sand much so as not to remove material. This allows the clutch to work properly again, and hopefully, not slip.

little box at the top of the motor that may correct the problem.

I think the contact points are items 21 or 22 in that diagrams.
The motor on my table saw start doing that and would not turn over. I
took it to a shop. He disassembled it, showed my what the problem was
cleaned, and blew out the area and it has worked perfectly for the last
14 years
