I have an older (Taiwan I think) milling machine which I use occasionally. I has a 2 HP 220 volt motor which has started to throw flames out of the bottom of the motor when I start it up, but never while running. It never fails to start just throws a flash of flame out. It has separate start and run windings. Is the problem the start windings breaking down? Can these be rewound or is it better to just replace the motor?
