As others have mentioned, more info on the engine is needed. IF the cam has already been broken in, then it sounds like you simply need to adjust the idle speed of the carb, which is fairly simple. If this is a NEW engine build that you are attempting to start, do NOT continue to start it and let it die...that will destroy the cam/lifters quick! If the engine has a roller cam/lifters, then it's not such an issue, but with a flat tappet cam, you MUST start it and let it run at 2000-2200 rpms for at least 20 minutes to allow the cam & lifters to "break in". Attempting to allow the engine to idle at a low speed will not allow the cam/lifters to be lubricated properly, and thus they will wear rapidly.
On a new engine start, adjust the idle speed adjustment screw IN(tighten) at least 4-5 turns to raise the idle speed, then start the engine, and adjust the idle to at least 2000-2200 rpms, and just let it idle. Make SURE there is coolant in the system, and check for any leaks while this is happening. After the cam break-in period, adjust the idle speed down slowly until the engine will idle properly. From thee, you can make any final carb/timing adjustments needed.
I e-mailed you a PDF on the adjustments for the Edlebrock carb, and it explains how to fine tune it.
