Not sure if people are describing the same problem. I believe my issue was from the piston not sealing or closing the hole completely. Cleaning restores it to normal and or the spring is too weak, or the piston is not aligned and rubbing on the way up and not fully closing the hole to block CO2.

I'm still operating fine since my cleaning and lubricant I added (described earlier in the thread).
