If it has caps, it's probably single phase. In which case it has that centrifugal switch in the back end. And if it is an open frame motor(with vents and a fan INSIDE) the switch can get a bit of crud in it and not turn on the start winding. In which case leaving it hum for a minute or so can burn up the windings.
Also, 3 ph wires go to the side of thge motor and directly to the feild windings. 1pf goes in the ned to the cent. switch.
IF it is a 1 ph/bad switch, you can bump start it with a cord would around the shaft. Turn it on, pull the cord. Like starting an old Briggs and Stratton, or tossing a spinning top. But talk about doing something you may not feel comfortable with... like hand cranking your PW...,
