Have a bench grinder that was given to me and runs fine if you spin it
up by hand - the capacitor is missing. Is there a way to determine what
size/part no. capacitor will work with a 115V 60Hz Single Phase motor?

HP?

3/4 HP, 3600 RPM


Likely a motor start capacitor.

I am looking at a NOS Mallory motor start capacitor on my bench --
it is rated at: 108-130 mfd at 250 VAC
