1999 9.9 Mariner 4 stroke--setting mix screw

I have a brand new carbeurator on my 1999 Mariner 9.9 4 stroke. When I picked it up the guy at the counter said something about setting the mix screw. I get the concept, but what am I looking and listening for to get the thing set up right? I sense a change in RPM, but only when I have the screw completely seated. As I turn it out, I don;t notice any further changes.

Anyone have any suggestions or explanations for me? The boat shop wants $50 bucks to get it set up by "ear".

Thanks,

I am surprised no one has had any replies for me. I usually hear something relatively quick. Was it a stupid question or a hard question or something?
