Don’t touch anything except changing your primary metering rod springs to half your idle vacuum when you your fuel pressure and float height. Get that right before changing everything and go one step at a time from there by your Edelbrock directions. You can eventually tune out the “Edel-Bog”, but get your baseline operating parameters (fuel pressure/float height/metering rod spring tension) set first before going any farther. That part of the directions for setting up your carb is so critical it should be posted on the first page of the installation instructions.
