It's a shame to see such a sexy gun go to waste.
Back in the SS2's heyday, this was a huge problem. If I remember right, the best thing to do was to spray something (I think lube) down the barrel and hope it helps the seal. Chances are you're screwed though, my apologies.
From the "back in the day" crowd, it was to spray WD-40 down and soak that "push" valve surface...that is, before we found out that WD-40 deteriorates plastic and rubber over A LONG PERIOD OF TIME.
(Emphasis was added to the end to calm the newbies who would get in a posting panic, saying, "It's going to eat up your rubber and plastic!!1!!OMG!!". It takes a while before you get the effect of it.)
That said, I'd try Silicone Lube spray on the valve surface (much easier if you have cut the barrel off, but still possible with the barrel on), and do most of what the other SS2 owners have said. Mine is over 4 years running, and it bleeds air when pumping up, but if it's pressurized quickly (i.e. pumped up fast), it 'seals' itself and builds up pressure naturally. I did spray WD-40 / Silicone on the valve surface, though. Still works great on the bottom of my Sawtooth.
Sheeeoot. That's a sweet color job, Bags. I'm stuck with my purple ano Metalcast. Time to get some different topcoat colors.
