My 91 streak sat unused for years. It shot fine for about 1000 rounds. Now the intake valve sticks occasionally. Can I treat this without disassembly?

what if we removed all the warning labels, and let nature take it's course?

about all you can do without disassembling it, is keep oiling it, and hope it straightens itself out. my guess is you got some crud working it's way through the valve. or, the intake seal is about to go. that's a more likely scenario.

I would knock out the two roll pins to remove front plug and pump arm. Inspect pump cup, replace if needed. Scrub and flush out pump tube with a rag on a stick and mineral spirits. Get as much crud out as you can... no sense pumping that stuff through the valve when you can clean it out properly.
