If the spring is too weak to push the piston out you can push it out with a rod inserted in the hole at the front of the cylinder. You have to file off the peening on the cocking rod if you want to remove it from the breech block. The barrel can be unscrewed from the breech housing if you are lucky, but it might be so rusted in that attempts to remove it could damage the barrel, so best left in place. Trigger removed as per usual by knocking out its pin from right to left.
If there is no power the most likely culprit is a poor seal at the rotating breech block. Sometimes this just requires replacing the leather washers, but sometimes it is due to a loose fitting breech block , caused by excessive wear of its thread, in which case there is not much you can do about it.
