Yesterday I took the burner assembly out of my smoker to replace a corroded venturi. It developed such a big whole that it was igniting and burning really close to the valve.
Well once I got it apart I noticed that the screws holding the venturi to the burner were too rusted to attempt removal so I patched the whole by wrapping it with heavy duty aluminum foil and cut some wholes in it to let it breath.
After reassembly and a good cleaning, I attached a full lp tank, then fired it up to test it fully expecting to have to makes adjustments to the breather but what I found was a beautiful blue flame that looked as good as the day I brought it home. I put some wood chunks in the box and filled the bowl with h2o and let her go for a while. She smoked nicely for a couple of hours but when I went out to check, it the flame was out. The burner knob still in the on "MED" position and could not here a "hiss". I turned the knob to off then on to fire it up. Again it ran great for a couple of hours then out again.
My gut tells me it has to do with the oxygen/gas mix, or the regulator but I can't figure out why it burns nicely then petters out.
Any thoughts?
Thanks,
Brian
