- Pull apart your starter (easy) and with an eraser or really, really fine emery clean off the brass on the spindle. Better conduction.
- Replace the starter bushings. They're probably quiet worn.
- Use 'Guard Dog' (
http://www.guarddogmoly.com/prod-moto.shtml) to lube your splines. Rub it in hard; the moly bonds with the metal. Best stuff I've found so far.
- Renew the dogs in the alternator. If they're original they've probably lost their effectiveness via shriveling up.
- Upgrade your ground wire with a 14 gauge wire. The original is as thick as a pencil lead.
- Clean, scour your trans. (brass wire wheel, pine sol, whatever) and spray it with this (
http://www.gibbsbrandlubricant.com/) before reinstalling. It 'quenches' the metal and will keep your tranny clean looking and less a dirt magnet.
Jeez, I sound like a walking brochure...
