My 110 3/4hp 1725 band saw motor blew it's start capacitor so I disconnected it and temporarily ran the motor by giving the pulley a spin by hand. It never went faster than 1200 rpm and the centrifugal switch would not engage, I assume due to the low rpm. Anyways, I was able to substitute a 220MFD cap I had on hand for the original 150mfd, and it ran normally - 1725 rpm and centrifugal switch engaged.
What I do not understand is why it only ran at 1200rpm without the cap installed.
