I will eventually pull the cylinder and valve chest, and see what modifications, better timing, larger exhaust ports, might be achieved. But first i will run it in a few hours with lots of lube and see if it helps.there does not seem to any other leaks anywhere. I also disconnected the piston rod from the rest of the mac hine and there is no binding.
