My old Murray rider (mfg. date 0092) will not start. Battery is good. It turns over intermittently. Some times, it turns over strong and continuous. Other times, won't turn over at all. When it turns over good and won't start, positive battery cable gets very hot. Don't know if my problem is: seat switch, solenoid, ignition switch, some of the above, all of the above. Any clues? Thank you.
