I have searched the forums and tried everything. Even brought over a guy who has been doing this a while and he couldn't figure it out.
Fridge sitting at 39 degrees. Set and forget method at 12 on the regulator. 12 foot 3/16ID tubing.
Usually about half the glass is foam. Doesn't taste/feel overcarbed.
As a ridiculous experiment, we put a 36 foot line on it and finally slowed to an acceptable pour with 36 feet and about 6 on the regulator. But obviously very slow.
So I left it alone off the gas for a week. Hooked up today back to a normal 12 foot hose, 39 degrees and started with the regulator around 2. Still foam. We'll see what happens as the night goes on.
