I'm still pretty new to kegging, but the transition from bottling has been everything I had hoped for and then some. It's so nice to pull a fresh draft beer at home and not have to deal with sediment and the subsequent rinsing of the bottle. In any case, my high pressure gauge reads that the CO2 tank is completely empty, which is clearly not the case. I initially though that it was because I have a dual-gauge regulator and that the valve nearest the gauge was closed. However, the CO2 should be running to that gauge regardless. Then, after checking out some threads online, I have come to the conclusion that the high-pressure gauge is pretty much like a radar detector: it really only works when it's already too late. Is that pretty much the deal? It appears that the needle in the gauge is not quite square, so I was thinking that I might be able to monkey with it. But if the end result is that it'll still read empty the whole time, I won't mess with it.
