Oh this was a fun one, the actual size head valve seal I needed was discontinued so I had to make the slightly larger gasket for a different model work. It took me a minute to think of using electrical tape to make the outside end of the main cylinder larger. Once I fixed that the gun was able to fire but still leaked out the exhaust end. I found a O ring that was out of place, re set it and she fired like new.
