In my excitement to learn how to rebuild a pair of Johnson Motors mounted on a 1974 Outrage BW, I removed the carbs from both motors and sent them to a marine repair shop to be rebuilt. While removing the carbs, the entire engine control system was discovered to have outlived its use. Removed the open control twin box and four cables---the same styles were ordered. Now my question, since carb function and controls definitly affect each other, what system should I replace first? I would appreciate all advice and comments. Many Thanks
