The repair strategy might not work. As you take up the slack with the eccentric adjustment, the crank may rotate relative to the other.
Lazy oaf/idjit that I am, once I've turned the eccentric enough to get slack to hop the chain over a tooth, that's what I do, in the direction of the needed adjustment. Then you rotate the eccentric back to see if you got it right, do it again if needed or tighten up the setscrews. Wear gloves and you won't slime your fingers. Removing and replacing the chain will drive you crazy.
Micromanagerial types note that it is easier to get closer to perfect synchronization with larger timing chainrings, but that can introduce a number of other frame clearance problems, so it has to be considered carefully.
