I have a crosman 150 that would not hold CO2 at all. I carefully installed a rebuild kit and found the exhaust valve to be bad. I used plenty of pelgun lube when reassembling. I fired about 15 shots thru it with no issues. Then it quit shooting pellets. I cock the gun and when I fire it, it sounds like there is no CO2 in the powerlet. After removing the hammer assbly, I was able to tap the exhaust valve enough the empty the CO2 out. I looked over the hammer assmbly and could not see an issue.
Second powerlet.
Like a fool, I lubed things up and tried a second powerlet. The first firing punctured the powerlet and pressurized the gun. I still get no CO2 going into the barrel when I fire it. I removed the hammer assmbly and again tapped on the releaf valve to release the CO2. It moved way too easy. As a matter of fact, I can depress the exhaust valve by pushing on it by hand with a punch. No CO2 is released at all. Now What? I have a fully pressurized CO2 gun, I cannot release the pressure, and I cannot disassemble it.
Any Ideas for me?
Thanks
