Actually, I believe I confused myself and this was a different issue. The one I'm thinking of was a forward/reverse switch going bad and when I pushed and held the button in I would often get the mag switch 'bouncing' in and out but not holding. The motor would start to spool up at this point. Sometimes it would engage, sometimes it wouldn't. As the switch failed over a couple of days it went from being a couple of clicks from the mag switch when trying to start to impossible to get running fairly quickly.
