It's normally easy to fix, Ig. If it's an Ingersoll-Rand style of valve,
there's a snap ring on one end that when removed allows the spool to slide

and slide it back in.
Lloyd, I am not fully convinced that it is a valve problem. It is more
likely to be a cylinder problem, because air is leaking through
exhaust. I will try a troubleshooting technique that I mentioned to
