Self-closing piston valve (brass fittings)

[Crna Legija]

take the spring out you don't need it unless you wanna fill form your camber.
can you slide the piston around easily with your finger, also did you cut a equalization port even with cast hot glue/epoxy pistons you don't need one it wont be air tight, if you have on your piston close it or make a new piston with out one.

if it still don't wanna work try a bigger pilot valve, with a piston valve this big you should be able to pilot it with a blow gun though and grease the hell out of it

what do you mean by fill form chamber?

[jackssmirkingrevenge]

it means do you fill from the side of the piston where the barrel is, or where the blowgun is connected?

"Form" and "camber" are both valid words - the spell check won't know they're wrong. There's some things that only proof reading will fix.
