I got a new bottle of CO2 (my first trade in) and all of a sudden, I can't seem to dial in the pressure on my regulator.....I have gotten to the point of it being two psi low or two psi high....luckily it only gives a little more head (who of us would complain about a little more....). I bought my regulator used (really, really used) and it has me shopping for new regulators....
is this normal or is there some other factor (like the higher pressure in the bottle)? Should I relax (not my style, although I try)? Should I buy a new regulator? If so, what is the best regulator (or what to look for)?
