Which way to turn mixture screws?

[supkylesup]

Hey guys just a quick question for ya.
I'm running way too rich and wondering which way do I turn the mixture screws to lean in out?
Also which one do I turn or do I keep both at the same amount of turns?
It's a 3.8l v6 with a Rochester dualjet 210
Thatnks guys

Each screw is independent of the other. Turn in to lean, out to richen. Use a vacuum gauge, don't guess. If it was running OK before, something else is wrong, maybe the float. The idle screws are just for idle, nothing more.
