Allright, I may have answered my own question, but generated a few more.
It had a "037 = cu13x" ecu and a 043 MPS.
If I read the chart right that won't work.
So, I put a "052 = cu16x" ecu in and it seems much better.
Now, both of the mixture adjustment screws on both ECUs have clearly been F-ed with. one was maxed out one way, the other maxed out the other. Now, normally I wouldn't start screwing with that stuff, but since its already screwed with, I figured I'd take a shot at it.
In combination of the mixture and idle speed screw, I have it idling about 1000 luke warm. I'll warm it up and see if it maintains, and obviously a cold start will have to wait till morning or later, but:
1) Are there any "baseline" settings for:
a) Mixture potentiemeter
Idle speed screw.
2) What am I missing?
The decel valve is completely removed and plugged if that helps.
