Carb problem-please help

I just had my edelbrock 600cfm carb overhauled, now when I start the car I can't get the idle below 1000 rpm. And if I try to adjust the mixture screws I can turn them in all the way and it still runs, the mixture screw adjustments make no difference at all.
does anyone have any ideas? The engine is a stock 350.

Sounds to me like your idle speed screw is too far in and it is not running on the idle circuit.

X2
Where do you get the 1000 RPM? A reliable gauge/meter?

You dont have to go up very far on RPM to have it start drawing off the main jets.

Sounds like you need to bring it back to whoever overhauled it and make them fix it. If you can turn the mixture screwes in all the way with no effect either it is not on the idle circuit or there is fuel getting in somewhere else
