I'd suggest taking the carb apart first and writing down all of the jet sizes including the air bleeds, emulsion jets, PVCR behind the power valve, idle fuel jet if it has them, etc.

Once you know what is in there then you'll know where to start. A lot of the tuning on a street car is done with the idle circuit so you probably only need some idle jets. Personally I wouldn't mess with the air bleeds until you really know that you need to make a change there. You should be able to solve 90% of the issues with a carb by tuning the idle circuit and the main circuit. Sometimes you need to change the PVCR.
