Old King Cobra

Well, I just got a BE king Cobra, and it leaks down the barrel. I'm guessing that it's the valve that's not seating. The leak isn't just a small leak, it leaks a lot on the back and front of the valve. I've tried lubing, taking it apart, etc.

Replace the Orings first off, also flip the cup seal over that might help

Here's a picture of the valve assembly.

I found out that I do need to replace the o-rings around the valve, but I don't think that's where it was leaking the most if at all. I'm pretty sure it's on one side or the other of the cup seal pin. Might I need to replace the seal on the inside (where the pin slides into)?

Hoo-Ra! That's exactly what I needed. Thanks! I think all the seals are dead. I think there might be some hope yet! I'll order them tomarrow!

B. E. Tips.

My kit doesn't contain the O-rings on the outside of the valve body. Suitable replacements can be found at larger hardware and plumbing stores. One thing to watch for on those is the body of the marker itself. There are several places where the body is tapped for various fasteners. Those places tend to have sharp ridges inside. Those sharp ridges nick the o-rings when the valve is installed and removed resulting in a leak. I recommend picking up a piece of wooden dowel, cutting a slit into the end and putting a bit of fine sandpaper into it. Use this to sand away the ridges inside the body. Maybe finish up with OOOO steel wool. This will save you a lot of trouble on those valve body O-rings. Avoid overtightening those fasteners in the future, if they are loose a little blue threadlocker will do the trick.

Title of this post sounds like a Nursury rhyme for paintball babies. . .

Well, my hardware store has quite a few o-rings, so I will look around for something for the outside of the valve. The problem was that the o-rings I think are just really old not really broken. Thanks for the help everyone. I hope I can solve the problem soon here!
