    Good morning.

    As Tom said, check the secondary of the coil at the tabs on the coil. The spark plug wires are just pressed up against the tabs and can get corroded over time. These Johnson coils are almost always good. The only bad one I’ve seen was physically damaged. These early Johnsons are great running reliable motors. After not working on early Johnsons for a few years I just picked up a 1923 B and a 1924 A at the Rocky Hill CT swap meet last Saturday.
