Are you sure you've got enough CO2 in there at 1bps? From those pictures the drop checker liquid looks more like dark green than lime green to me.
Definitely think that's an area of issue mate yeah. Do you know if having the cylinder on its side affects the pressure? I've noticed sometimes it's lower than I set it to with the valve but wasn't sure why. Might force it upright. I think it's pretty lime green I'll take another shot when I get in!
