I got 2 coke kegs off of CL last week and they have not been used in years (~8), the guy told me. I was trying to get the posts off one of them and they wouldn't move. I was using a wrench which is a little tricky with the pins. My friend gave it a go and broke one of the pins off the liquid post! Is that post still going to work? I still have to get it off though, any suggestions?
