Jacob, thanks for posting and welcome aboard!
Spring in, I can barely get the valve to move. I’m not a girly man, but dam I’m sure I can bench press 1bar=14.5psi (unless my math is whacked)

Spring out, everything moves silky smooth.
Enough already, I am buying a stock spring but PP doesn’t sell them, anyone know a source, PM me, else PM me in a few days for a source.
