So we can believe in the improbable that both carbs were, as you say, "messed up" with the same defect or more likely that as much as this sounds like a carb problem it is really something else.
He could take his components, carb, mag etc, and run them One at a time on another engine that has been running well and see if he can duplicate the problem, thus isolating the cause, but that is a lot of trouble.
