The two screws on the bottom front of the carb is the idle mixture adjustment. No carb has a "set amount" for them. They are set with a vacuum gauge. When the gauge has it`s highest vacuum reading it`s correct.
Afterwards you`ll want to set both sides equally. Do this by turning it in and count the amount of turns until it seats lightly. If you seat it tight it can do damage. Then turn it back out the same amount then follow on the other side. If you don`t have a vacuum gauge then set them to where the engine idles the highest by tachometer and runs the smoothest, if no tach, do so by ear. Turning them in leans the mixture. Turning them out richens the mixture.
