I am in the process of doing my first ignition overhaul on a Johnson QD-16 that I bought ( I have never done this before) and have a question about the cam. I noticed after pulling the flywheel that the cam was riding high and not even in contact with the points. After removing the magneto plate found that the cam sits upon a thin bronze washer which in turn rests on a spring. It seems that the spring is pushing the cam up to high and that the cam freely moves up and down the crank shaft. I am not sure if this is a common finding and what the correct solution is as there really is not anything I can see to hold the cam down. Any ideas would be greatly appreciated!
