All good to know and useful information, however one has to start with a good cylinder.  All wasted if cylinder is excessively worn  or scored. Fortunately, the modular design of the Early K Model Kiekhaefers  cylinders can be removed and replace with better cylinders from a parts motor,  Boring to an oversized is not an option as oversize, rings and pistons were not offered and were not needed.  Mercury did it their way.

Once a good cylinder AND piston are in hand then it is time to set ring end gap.
