Hey everyone, need some help A.S.A.P. I am trying to tap my keg using CO2 and am having problems. I am following the directions from http://www.kegworks.com, but I am not sure where the “adjustment screw” is. I have identified the drum screw (big bolt on front of regulator) but it says I am supposed to have a P.S.I of 10-12 before I attach the coupler to the keg and turn on the gas, but I am unassure how to do this. Any help would be appreciated, I have the keg and my mouth is watering, need help A.S.A.P.
