whistling venturi burners-and back flaming

Great sense of humor! Thanks for making my day! I have another question
about raku burners though-occasionally when I raku, the burner I have has
a small "back flame" -maybe a half inch or so just at the very back of
the nozzle-looks like a small leak but doesn't occur anywhere near the
adjustable disk at the back of the burner- I can blow it out
physically, and have tightened up the nozzle as much as I can-what is
causing this? Any ideas? Will it distroy the burner nozzle in any way?
Thanks, Claudia
