So, when you first put a keg on, it runs fine. Then you take it off, cool the
keg, connect again, and out comes foam. To me that sounds like the
temperature drop has increased the pressure in the keg. At home, with quite
different setup, I never connect the gas at all, until I see if the keg has
enough pressure to pump the beer out on its own. Only when the beer flows
very slowly do I think of adding CO2, and even then I don't leave the gas
bottle on, just give it a pffft or two. When the keg is nearly full, there is
very little air space, and a small amount of gas makes a large difference in
the pressure. When the keg is half empty, there is more airspace, and a
longer pfft is warranted.
If you have a regulator in your tap, like some of the good bars have, you can
also turn it to a very slow flow, and patiently pour the first pint or three.
I'm sure others will pipe in with more exprience. Until then try with no gas
at all, and hope you can pour some Xmas
beer anyway
