Idle speed., o.k. cold, high (2000-2300) warm Options

[DuckRyder]

Going to start trying to figure out the idle speed. It idles quite high when warm and properly when cold.

Is this the type of thing that a ECU/MPS/CHT mismatch can cause? (IMG:style_emoticons/default/idea.gif)

I'm going to start running down pblanders page and checking everything, is there anything else that comes to mind?

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

2) What am I missing?

The decel valve is completely removed and plugged if that helps.
