ahh - that's different - non- return valve in the filler. Fill it muzzle down, that often does the trick and tap it a bit to settle the flap valve. Also bleeding rapidly also helps the air rush blow the valve back down to seal
If you do end up stripping, you can put a little spring under it to hold it closed in any position.
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
