not sure what you're trying to do but the idle air bleed and idle jet size are pretty close on those carbs, keep in mind there are more than one bleeds that feed air to the idle circuit. afb's have more air bleeds and emulsion bleeds than holleys. the main metering on those edelbrock electric choke carbs is too lean. the idle jet should be around .037" but can be opened up to .040" if need be.
