My new keezer is shooting out just about straight foam. It's been carbing for 8 days at 12 psi. I even turned down the regulator to 8 and it is still out of control. It is set up the same as my old Kegerator so I don't know whats the deal exactly. After a few minutes about 75% of original foam is gone, but it's still flowing way too fast. 5 ft of line into the tap that is about 3 inches above top of keg.
