proper carb adjustment steps

[shelby987]

For those of you following my previous saga, my rebuilt economaster carb is on now on my truck and running very well, but I am having difficulties adjusting the carb, the holley manual is not very helpful (it references smog equipment that my truck obviously does not use).

I have tried to set the idle using the idle screw on the throttle level, when it starts it runs at 2k, if I turn it down it won't make much change until it gets to a point where it will stall out. I thought maybe I needed to wait until the engine was warm, so I waited until the engine hit operating temp, turned down the idle screw, and got the engine to just below 1k....but if I rev up the engine a couple of times, when it goes back to idle, it sits at between 1,600 and 2,000 rpm again.

I thought maybe I needed to adjust it via the mixture screws from there....and I seem to be chasing my tail.....what are the proper steps to set the idle and mixture screws????
