Ok so I took out the bake burner and checked it for obstructions and did the BB thing . I could blow throw the tube with out any problem.. The brass orifice had no obstructions and showed no sighs of any oxidation. Could any one tell me how large the flame should extend from the burner tube when working properly? what could be next? The broiler flames extend quite a way from the burner tube, if this is how the bottom burner should act i would like to know?
