I recently bought a Tippman 98 custom. I installed a dual trigger, and since I've had a problem with the cocking mechanism. When I pull it back it doesn't reset far enough forward to fire when I pull the trigger. I have to push it toward about a quarter of an inch before the trigger will work. Everything seems well lubricated and all the pieces seem to be in place but it still doesn't work. Will putting air pressure into the system fix this or is it a problem with the mechanism?
