Everything I have read says to push beer at around 12 psi out of my cornies, maybe a bit higher for commercial kegs. Problem is, from effectively 0 all the way to 15 psi, I get nothing but foam. It settles out eventually, and I have poured a half glass, but it is really getting frustrating.
I'm wondering if my regulator might be lying to me? I've noticed that after I've poured 3 or 4, the foaming goes down a lot and I'm able to pour a relatively decent beer. This makes me think that my regulator is over carbing my beer, but even if I have it set to a pressure low enough that beer almost doesn't flow and I purge the keg, I get foam coming out instead of beer.
I'm guessing this is one of those things that everyone else has learned and I haven't caught onto yet, so I'd love even the basic advice.
