After some digging I determined that my malfunctioning ODO was due to the "trip" button spring thingys being worn out. I slipped some hard plastic (cut from a blank CD spindle cover) over these little "spring" strips to restore firmness. Worked like a charm!

Now my speedometer doesn't work though. It looked like there was a small metal pin inside the rear "bowl" of the speedo needle that set inside a plastic controlling grommet. Should I add a bit of sticky inside of this little plastic circle to help grab the rear speedo needle? (Hard to put all these pieces into words... sorry if it's murky).

Anyway, pics of my ODO fix!
