Need Quick Fuel carb tuning assistance

I know that the emulsion ports in the metering block bring air into the fuel. Also the IFR jet in the upper bowl side of the block restricts the amount of fuel going to the idle circuit. BUT, if I were to close off one of the 3 emulsion holes, what would that do? I assume it would put less air in the fuel and it would run richer? Am I even close.
