Jack you want to valve to just close at 45 degrees before bottom dead center
in the direction you want it to run. If it's turning freely in that
direction and stopping when you try to spin it the opposite direction your
piston to cylinder fit and valve seal are perfect.
It takes a minute or two of spinning the flywheel to get the inside of the
cylinder up to temperature. It sounds like you'll have a runner there!
