Most of the seals inside of the gun are made from hard plastics like nylon that really wouldn't wear out easily or harden and crack, testament to the to 'no o-ring' design, so I wasn't quite sure why it leaked.Īnyway, I lubed the 'seals' up good with some lightweight silicon based grease, and then as I was re-assembling, my eye caught that '0-ring' like seal around the threaded portion of the valve that you twist into the body of the gun (with pliers) to hold all the valve parts inside. I disassembled it as far as I could, then found your instructions and used then to disassemble the valve. It would de-pressurize in about 30 seconds. It has been stored away for at least 20-25 years, and when I got it, the gun leaked like crazy as soon as I punctured a fresh CO2 cartridge. Hey, I have a Daisy CO2 200 Pistol that was my dads when he was a kid.Īfter his father (my grandfather) recently passed away, we found the pistol in some of his stuff.
