yeah i been talking to crayvn about this, and as far as i can tell thats not possible on a gtt unless you crack a secondary ring of oxy. i always see yellow in the flame tips pretty much unless that is done. even cranking the main oxy way past the point of efficiency i still see yellow in the tips a tiny bit.
