Re: Johnson 1961 10hp flywheel
I have a buddy of mine with the same motor and he complains about the same thing. His best solution is to have an extra pair of hands and a long screwdriver. One person holds the spring-loaded cam in place with the screwdriver through the inspection window on the flywheel, while the other person lowers the flywheel onto the shaft. Once the flywheel is in place, you can make any point adjustments through the inspection window. I haven't done it myself, but was told by my buddy about this "gotcha" since I had a QD-21 for a little while. I never got around to changing out the points & coils on it, though.
