Need some help here. I put together the below portable kegging dispenser (based on a design found here). Keeps the kegs cold but unfortunatly beer pours out straight foam. I have tried several things (replaced hoses, chilled the lines, messed with carbonation) all to no avail. Any advice? Perhaps its something with the faucet? I appreciate any and all help. I'm supposed to bring this thing to our annual dudes weekend out tomorrow.
