I just purchased a 2 keg system from KewCowboy. I kegged an IPA last Sunday and had it sitting at about 15PSI. It seems as though whenever I try a taste, residual beer comes out of the cobra tap, even after the value is shut off. I have to actually take the pin lock connector off so I don't have a huge mess. Has anyone else had this issue before? Also, my beer has a lot of head but not really any carbonation (body) in the actual beer.
