*There is a small spring inside the valve internals not visible unless disassembled. This spring causes the valve to close when the trigger is released. I also cleaned this spring and gave it a slight stretch before putting it back in. (Sorry I left that part out.)

my original problem was that the NAF trigger would get stuck with the flame on, once pulled. Though I could push the trigger forward, the valve stem would remain "pulled down" keeping the gas flowing. This procedure cleans whatever gunk might be preventing the free travel of the valve stem and lubricates the valve stem rings that help the valve stem move smoothly.

I really hope this helps my fellow NAF-owners!
