Right, a couple of questions now I've had a chance to have a good look at the stuff I bought at the weekend:
1) the previous owner provided 2 8g CO2 cartridges. The dispenser really should take 16g but he's lodged a piece of shaped polystyrene into the end of the cartridge holder in order to use the smaller cartridges. Firstly, am I safe to use it like this to use up the last 2 cartridges? I would have thought there'd be scope for the cartridge to wobble and leak as they have different girth a (Oo-er)! Secondly, where is the cheapest place to get 16g cartridges? I only want to buy 2 bungs and a box of 5 cartridges so don't want to pay the "usual" �ã7 postage cost.
2) I currently have an easy keg full of beer that I plan to tap on Friday. Do I just take the red bit out of the bung and attach the tap into the rubber black bit, or do I need to replace the bung with one of the reusable ones I've got?
