Odd air/fuel mixture screws

I have the newest version of the holley 390 4bbl. When I screw the idle circuits in to like have a turn out from seated I start to smell a strong gas smell. I thought screwing the circuits in would lean it up. Do these circuits meter fuel or air? Also after completing the team rush my jeep idles best at like over 20degrees advanced, and doesn't run so well when I start to retard it from around 20 degrees. What does this mean. I haven't got it out on the road yet, but just revving the engine it feels more powerful than before team rush. I am anxious to get out on the road, but thought i needed to get timing and the idles circuits right.

Thanks in advance for your help!!

IIRC Holley adjusts the air, opposite of common.

As for the timing, find true TDC using a piston, not the balancer - it may have spun.

Is this what yours looks like?

Not sure if this is the "Latest version" as this seems to be around a long time.

I searched the Holley website thinking they would have the latest description.
The Holley website lists some great technical manuals for free. Holley Performance Products Technical Library

Such as how your Holley works: http://www.holley.com/data/TechServi...ech%20Info.pdf

And how to set up a 390 Holley: http://www.holley.com/data/Products/...199R8108-2.pdf

They still look like common house hold variety idle control mixture.

Thanks cutlass I have been thinking it metered gas since day one. And I checked TDC last night and it was right on w/Timing mark.
