Re: Johnson Super Seahorse 1963 75hp
Seahorse, Each set of points fires 2 cylinders. However, they do not operate independently. The cams overlap such that one set of points opens, and the second set opens and the plug fires.
There should be a timing mark on the distributor pulley base. One set of points should open when ths mark matched the mark on the pulley. 90degrees away is the second timing mark on the pulley base. the second set of points should open at this spot.
