I have a China bench grinder I got second hand, has worked great for several years. Now it tries to start like it has a bad capacitor but there is no capacitor, if I spin it REALLY fast it will go, but REALLY fast means winding a strap around the grinding wheel and pulling it as fast as I can. Shaded pole motor? Is there any fix?

In my opinion If it has a name then your best chance is through that outfit, if it’s unbranded or a unknown name then your probably best to just replace the unit as a whole. Good luck

Have you turned it upside down and looked under the bottom cover. There is often a start cap hidden there.

Have you looked inside the base for the capacitor? If so and its not there take the whole thing apart for inspection, if nothing is obviously wrong, pitch it.

Does it have a centrifugal starting switch? If the switch is locked in the open position, the motor will not self-start.

Probably split phase vs. capacitor start... capacitor increases starting torque, not an issue w/ a grinder, etc. (vs. say an air compressor).
Bum/stuck/dirty starting switch or (less likely?) open starting winding.

If it has a centrifugal switch it will be inside the motor. It is not a matter of lubing, it has electrical contacts that can stick, I've also seen them break and melt.
