This is going to be long post so please stick with me! Ive had a keg kit for a long time and never had any foaming problems. We just had a keg of Ying with an excessive foaming problem and I could not fingure out what the problem was. I have 4.5 feet of 3/16 id for my beer line. I have balanced my system and my PSI said 13 when I calculated it. I have my homebrew connected and all I get is foam unlike the ying it was about half and half. I am going to Kegworks today (I love having them local) and I am going to pick up 6 feet. The height from the middle of the keg is 1 foot. I think my homebrew is over carbed so I am going to spend the day bleeding the system. Also I am going from 5/16 gas line to 3/16 for my home brew coupling can that cause trouble? Sorry for all the questions
