Okay...

I managed to get to the stove top burner assembly by removing the face plate
that has the LED panel in it.

I lit the burners and applied a soapy solution around the valves... no
bubbles...

Used my bio sniffer (nose)... seems like the smell of gas comes out of the
air tubes... it seems that the propane is injected after the valve into
these tubes which go to the burner orifices... when the propane is lit the
flow of propane creates a draft that sucks air into these tubes....

So I'm wondering if there is some adjustment to this air/propane mix tubes
that would keep the propane from wafting back into my nose?

Anyone know how to adjust these things?
Would cleaning the burn orifice and tube with a 'bottle brush' help the
flow??

Thanks,

Bill
