I am new to kegging and had 1.3 kg co2 bottle arrive a couple of weeks ago. Set it up with a quality Italian regulator to purge and carbonate a krolsch in a 19 litre corny. Went well and the krolsch carbonated well, but I have two issues. 1) after dispensing a few pints the gas appears to have run out with the regulator showing co2 empty and the other dial showing zero psi. It was a full bottle so should be enough to carb and dispense 6 kegs at least. I also checked fully for leaks at the begging before carbonating with special spray and found none. Also as the keg carbonated well and quickly i imagine that makes a leak unlikely. I think there may be gas still in bottle and the problem could be with regulator. 2) to check above I wanted to remove the co2 bottle but first when trying to close it to switch co2 off, I found it was completely stuck, it wonÃ¢â¬â¢t turn either way. I left it out in the hall to warm up overnight and tried again today but itÃ¢â¬â¢s stuck solid still. Has anyone experienced this issue? How was it resolved? Cheers.
