Has anyone had problems taping these cans? I have a can tapper that has worked well for me on several occasions but today I was unable to get Freon out of two cans. I even tried another can tapper without success. The guy I was trying to help bought the 134 at HF so that maybe the problem. I'm used to working with 30lb cans not 12oz could I be the problem? I do understand that you screw the needle in all the way and then back it off to withdraw Freon.These 12oz cans seem to be a real PIA.
