edelbrock carb please help

[orangeEX]

i got a used one with no instructions i think the screw in the top is a needle adjustment and i figured out the accelerator pump theres a leaver on the side if i move it with it running it will die
looks like a choke lever quad runs pretty good i just want to dial it in..i know how to adjust jets and needles on standard carbs just need to know all my options on this quicksilver II

thanks
wes
