Okay, been having issues with my '82 720KC. It ran fine for a few months after I bought it, then it stopped wanting to start (no power from battery) after it got cold out. Managed to get it started a few times by jumping it and then it would start fine by itself up until today when it stopped wanting to start because of power again.
The other problem I'm having is the idle is all jacked up. Part of the time it will idle around 1k but the other parts of the time it will idle around 2k even after it is warmed up and it will sometimes go down to 1k only to go back up to 2k at another time. Today it was idling fine for a bit, then started to idle at 2k all the time, then at a few moments it jumped the idle up to 3k until I tapped the pedal a bit and it would drop down to 2k.
Any ideas?
