.  Thanks for the response. That's what everyone told me originally, and that makes sense (too much carb, it shoots out, carb is released = big head/flat beer). So originally, that's what I did. I reset it and put the psi around 00 for two weeks (I've been messing with this for almost two months). But even at 00, it was still the same problem, big head no carb, which is what makes me feel like there's something else wrong here.  I'll try again, but if anyone has any other ideas, it would be much appreciated.
