I gave the cylinder a few more degrees here and there too, while I was at it. Cylinder is now maxed out. Near enough 72% as well.
Ready to put the cases together tomorrow. Seal and new 9 ball bearing in. Not changing anything else. Was all done last year. Might have to go Christmas shopping some time tomorrow but still on for running soon.
Going to run for now on still ok rotary Pinasco race crank. Inlet is so big it shouldn't make much difference.
One side done. Other to do.
Metal getting thin in places
