To tune a 2-barrel Holley carburetor, start by ensuring the float levels are set correctly, as this affects fuel delivery. Adjust the idle mixture screws for the best idle quality, typically by turning them in until the engine stumbles, then backing them out slightly for optimal performance. Next, check and adjust the choke operation if necessary, and finally, make sure the accelerator pump is functioning properly to provide adequate fuel during throttle transitions. Always test the vehicle after adjustments to ensure proper performance.
