Ok i have a classic setup on co2 with aci expansion chamber. That being said and done, plugging gas into the gun has no effect. The sear doesnt push down and engage the trigger. I can hear it gassing up, but to no avail. My powertube has a funny spring for a spacer. Do you guys have any suggestions? (Airline is clear, i just tested it by running water thru it)
