Soooo, after fighting loads just to get CO2 working ok coming on and off at the correct time and pressure I then had to turn it off for 6 days. It is now v. broken. I haven't been able to get the second gauge on because I have no spanner. When I leave the set not plugged in the pressure slowly goes up to 2 yet not many bubbles seem to come out. If I try changing the fine adjuster nothing happens. I plug in the solenoid and the pressure drops to the bottom. The CO2 bottle is almost new but I go through one every few weeks (!) I'm thinking I should just exchange it for a new one at the place I got it. I don't have the receipt or box though so I'm hoping they'll go for it. For now I've unscrewed the reg from the bottle as I was coughing alot. Could be hayfever and just going back to Cambridge but I never normally get wheezy like this.
