wow I think my gun is just f'ed up but whatever. Now I got my stuttering problem fixed... now its my cyclone

whenever I hook up my air (co2) to my gun, and then shoot it, the cyclone jams. no balls, but the manual pump thing goes limp (can push it in a pull it out like there is no spring, just an easy slide). when I take the gun apart, the clear plastic rotating thingy's 'long' end is stuck around the place where there is that metal 'hook' and the spring is all compacted on that little hollow cylinder and is stuck pushed in untill I take the little hollow cylinder that the spring goes it out of its original place does it return to how its supposed to be. I can hand pump it fine when I re assemble it, but if I hook up air and try to shoot it, it mal functions...
