Ok I was trying to help out a friend fix his Tippmann 98 custom the other day.
It had been sitting for a while all the O-rings are good powertube not cracked or damaged from what I can tell.
I oiled it up good still no luck.
Air her up and all we got was a fire fire "full auto" I adjusted the velocity all the way in and out with no diff. in velocity.
Had a good fill of air over 2k psi.
I haven't worked on much less taken a tippy apart in sometime.
I could be way off but Im thinking a new spring kit or new Valve are in need.
looking for any input that may help get this up and running.
P.S. I need a Powertube for a Response Trigger,
Cyclone I need the hose, mounting screw, Mounting Bracket.
