Bad news probably, start winding switch may not be cutting out of circuit. By the time you buy one, ya might wanna go to Graingers or maybe Northern Handyman for a compressor motor. If it is a dayton, you might call graingers for a replacement part, they carry several other lines as well. Check the switch first of course, but if it is starting (without a manual 'shove') it is likely the start circuit not cutting out. If you have to shove it, the start winding is gone. Either way with that motor, it's likely cheaper to replace than repair. [Linked Image]
