quote Garry in Tampa:
An old Johnson dealer I knew (George Cheatem) had a large ring that took the place of the rope sheave. It was countersunk for the johnson’s #12 X 24 screws and tapped in between for standard quarter twenty screws. It allowed him to use the standard flywheel puller on the antique Johnsons with little danger of damage to the old impossible to find #12 screws. . . 🙂
Garry,
That is a great solution!
