Not sure what the difference between this and the other posted ALOCS CS-G04 is about. This one has some heat shrink added on my part because I felt the crimp needed some more relief so they don't come from the factory that way. There's an interesting elongated cutout in the bottom of the base/body that makes me believe I could make a copper heat shunt that goes into the right angle fitting. I've tried unscrewing it and it indeed can be unscrewed, that aside the burner gets plenty hot anyways so I assume it just needs more of a thermal path into where the jet for inverted operation. It does not really like operating inverted but if it gets hot enough it'll take liquid feed for a few seconds before it flares due to the liquid being sufficiently chilling.
