That's a quickly taken picture of the internals, I had a lot of leaks, mainly at the connections so I gooped and epoxied everything. Now that the leaks are fixed though there's two more (hopefully final) problems. One, the internal spring is rusted most likely, I have to hold the firing pin forward with my finger to keep it to pressurize. I tried a normal rubberband but I guess it was too weak, it was pretty thin. And two when I do hold it and pump it a few times (air only) The back of the tank, at the firing pin, it leaks and theres a little gray water. It doesn't smell like mold though.
This is the firing pin and some water that leaked out on it (though the gun is mostly dry I thought)
but I'll get a video when I get someone else to hold or pump it (it's a two hand thing, and I can't record without a hand)

and here is the black stuff

Also, when this is all said and done I'm going to fill the deadspace in the shell with Epoxy Putty to give it some weight, make it a lot more durable, and because my dollar store now sells epoxy putty. Is this a good idea? I'm getting an ss 200 soon I'd like to do the same to to fix the weakness problems as well as replace all of the tubing (darn pinch valves) once I get it and find out what size tubing I need.
