Tuning Benjamin Taurus 357 losing air

Good evening,
The rifle mentioned is a Bulldozer not the Taurus, when it came in the Bulldozer was already in a state of disassembly. THe probe spring was broken in 2 pieces and jammed into the ledge of the hammer and the cocking pin, it showed signs of severe gouging as the hammer was tried to be cocked and fired this ultimatley prevented hammer movement. The valve stem was bent and preventing the valve from closing. As well I found the plenum pushed almost completley to the front of the tank, and the oring seal blown out, this is indicitive of over pressure or hot filling and would prevent the valve from operating at peak performance. I let arizonapcp know the status. Even though not the orginal buyer I rebuilt the entire Bulldozer arizonapcp was very gracious and covered some of the cost and I carried some of the cost under warranty. His Bulldozer was sent home hitting 323fpe and just awaiting to hear back him.
