Hi.
My Mini GS is leaking from the bottom of ASA, precisely from the pin that on/off lever pushes. Strange thing is that this is happening when the lever is flipped off, when i flip it on it stops and the mini shoots normal.
Besides that, gauge is not zeroed, but that's just a little inconvenience, and I'll replace it shortly (unless there's a way to zero it).
I've read the sticky, and found nothing that would solve this. Tried to clean the pin and lever, tried to lube it with a drop of oil, still leaks.
Did you check the orings inside? Especially the ones on the reg seal retainer.
