Adjust the air mixture on the oven burner. This is a metal part where the brass orifice is mounted on the burner valve. You loosten the screw on the side of it enough to be able to slide it back and forth. Get a flame going and move the barrel until the tips of the flame in the burner is completely blue...no part of the flame should be orange. Once that is done tighten the screw . automotive brake fluid is an excellent soot cleaner. It smells bad so use it with a lot of ventilation.
