Quadrajet APT Adjustment Confusion???

[savatreatabvr]

I bought a (supposedly) remanufactured 800cfm Quadrajet for my 1973 C20 454 and it was screwed up from the beginning. It never ran right (as seen in my other threads) so I tore it apart and fixed several things (as seen in my other threads) but I made the mistake of taking out the APT adjustment screw without counting how many turns it took before it was fully removed. I've read several articles on how to adjust the APT but one says one thing and the other says another! That's the only thing left that's stopping me from bolting it on so does anybody have any helpful hints on how to adjust it other than "YOU SHOULD HAVE NEVER $%^#@* WITH IT IN THE FIRST PLACE", lol!

It's the red arrow below!
