[TheForge] burner adjustment

[Gladish Family]

So, I went to the shop and built a venturi burner.
Playing with it mounted in a vise I found that I could get a good flame and
it would hold it as long as it was neutral, but that the closer to the
venturi I moved the orifice, the more I had to choke it. To my eye, the
quality of the flame was similar, but is there an advantage to moving the
jet closer or farther away from the tube?
BTW, thanks for all the great discussion and tips, Frosty et. al!
