If your system is set up properly, that is with no fluctuation of temperature and correct pressure, you should have limited foam while dispensing. Coors Brewing Company packages draught beer with a carbonation level of about 2.8 volumes out of Golden. This may be lower out of the Virginia facility (2.6). Topgun, you should target 38F at about 14 PSIG since your Coors Lt. is possibly at the lower carbonation level.
Remember, drop your glass away from the faucet so that you can watch the flow from the faucet. If the beer is foam and it goes to the bottom of your glass, do not pour clear beer on top of it. You will produce more foam if you do. Dump out and start with clear beer.
