The 750A has 2 idle adjusters, the familiar 'knob' in front of the carb bank and a second ' in gear' adjuster between carb2 and 3 ( facing to the back ). Do you have a Clymer Manual on the CB750's?, as it explains well how to balance the idle settings on the 'A'....
If your sure it's a carb problem; it's ignition,
