Edelbrock carb 650 cfm performer

I was wondering how do u adjust the air/fuel mixture on the edelbrock I know it has to do with the two screws on the front of the car I just wanna set the fuel side feels like to me the carb is dumping way to much fuel down into the motor could this be done or no looking to get somewhat better gas mileage

The screws on the front only set the idle mixture. Cruise and power mixtures are controlled by the rods and jets.

The manual has a detailed step-by-step procedure to tune the carb. Follow it exactly.
