Invert Mini GS not working

[Krazycol]

Hi just brought a second hand mini gs by post. Just put a full 3000 psi bottle on flip the ASA switch on an gauge goes up to 180. Fire once an pressure drops to just over 100 then fire and down to nothing. Can someone please help.

sounds like the ASA / reg on the Mini is not engaging the pin of the tank valve well

Cut a small piece of plastic card and placed between pins as suggested in other forum, an it works fine now. Can you get bigger pin assembly do I don't have to do this?
