My recommendation would be to try it out just as it is out of the box. I would not take it apart and change anything. Maybe I got blue eyes, but I actually believe that when I buy something I get it as described. As you seen from my own thread I have just installed the same carb, not plugging Holley here. I hope to get it as described from any manufacture, or private add.
I had to make it a little richer on the idle mixture screws to get it to idle as I want though.
I hope you will be happy with It Snake!
