YOU GUYS... WHAT GURU'S YOU ARE!!!!
Cheers for the advise, seems it was the gas mixture.
The chiller is the same as the one used by pubs below the faucet, chills to a tasty icy coldness.
The Keg is kept through the wall, cool dry and out of the way.
I have "real ale" on my manual bar pump from a firkin, no need for gas or chillers.
The larger is for those warmer "refreshing" nights.
Cheers!!
