Need CO2 help
Swapped empty tank for new, employee at store detached/reattached regulator under my auspices.
Opened CO2 at my home, it's now shooting out of the hole in the attached pic, this small keyhole. That's an adjustment screw? This phenomenon is new to me...
Please help/advise. Is this a matter of tightening (I tried) or is something amiss? Thanks guys.
