I finally got the Shee engine back together. Cylinders measured out good enough for a light hone and new rings on factory pistons(64mm). All new seals and replaced all o rings in the cool-head,and replaced all gaskets. I went to check for leakage,I was told to put 6psi of air pressure into engine and should hold that for 6 minutes.I put 6psi of air pressure in engine and it leaked off 2 psi in 6 minutes!! Is there a certain list of protocol to do a leak down check or is there something wrong with the engine,and will it still run like this?
All feedback is welcome.
Thanks in advance
