Your floor nailer is as basic as it gets, the seals have to be gone. Did you try some oil in there to seal up the leaks? Take it apart and see what is going on in there. I sent you a schematic on it, no spring, just a bunch of seals and rings. The Bostich stapler? How much do you want for it?? Only kidding. Mine will machine gun on me at random, It is just the trigger pressure that does it to me, you can hold it just right and it will machine gun, but use like it is supposed to, and it won't. Once in a while it will bounce off the work and fire again, but usually only once. And that is because you let go of the trigger and the bounce causes your finger to go back on. Check this out. Hope it helps.
