I know it's not lawn equipment but figured I would ask. I have a small Craftsman air compressor that just quit running. When I flip the switch it just buzzes and I get a puff of smoke out of the motor housing. I took the cover off and released the pressure from the tank. With the pressure off I can manually spin the motor over and it will start up and run until it reaches pressure but will not start back up automatically. Any ideas? Is the start capacitor bad?
