Also, the top sealed GAS burners puzzle me....
There is one large opening, about 1/4" inches in diameter in the
circumference of each burner. The hole is to the rear, many times
larger than the standard burner holes and is not near the spark
igniters. The problem is that a large volume of gas jets out of each
of these large burner holes, sending a small finger of flame up the
side of a pan, sooting up the pan.

What was the purpose of these larger holes?


All gas burners have a large opening to admit air which mix air with the gas
before combustion. They generally have a sleeve in the vicinity that can
adjust the size of the hole. Move the sleeve until the flame is the standard
blue.

Without Oxygen, you'll get a yellow flame signifying incomplete combustion
and that will, as you found out, generate soot.

Anyway, your problems about "F1" and this weird flame are not connected.
