I'd stay with carbs since you already have them. Get them overhauled then jetted correctly on a dyno if possible and you should not have to "fiddle" with them at all as long as you drive the car regularly so the goop doesn't form inside from the terrible gas we have now. If the carbs won't stay adjusted, they may be shot from corrosion/ wear/etc and new ones would be required. Good luck.
