Hey all. Just joined up to ask a question about my Crosman 760 Pumpmaster. Built in 1977, the number tells me. I bought it new, and it worked like a champ for decades. Just dug it out of storage, and when I pumped it 8-10x, the BB would not leave the pickup magnet. I just figured right away it needed a rubber cup etc so I bought to rebuild kit. New cup, 3 new o-rings, and new valve. Swapped everything out, and....no change really. SOMETIMES it will work correctly (only with 8-10 pumps) and it will hit a target, though not with much impact, it sounds like. But then, sometimes 8-10 pumps won't move the BB off the pickup again: just like before the rebuild. Sometimes it moves the BB, and I it's gone when I check, but....when I tilt the barrel up, the BB rolls back to the magnet: not enough oomph to actually leave the barrel. It's still inconsistent. Almost like the parts swap did...nothing. And...shouldn't I be able to shoot (although weakly) with...2-8 pumps? Right now, that's not the case.
Thoughts, other than "send it to a pro"? I called and they want more than it's worth, frankly.
