I don't think there is a gasket, have you checked the torque on the cone fasteners?
That's not a gap but the reflection of the flames at the rear. For a split second I thought the same thing. I also would suspect an internal leak/broken needle and the kero plug solenoid sticking open, as George suggests, is worth a shot. And as you know, I'm no expert
