How did you make the flame "roar"? Change the orfice in the burner?
B.t.w. In my '82 Westy I removed the fibreglass insulation in  the wall panel behind the fridge. This improved the fridge performance noticeably. (It didn't occur to me to to do before/after delta T measurements). I'm guessing the insulation removal behind the fridge might help in two ways: More room behind the fridge so more air to circulate. Additional cooling of the air behind from the now non-insulated metal wall. My '82 is white. This might not work on my gold color '85 or any dark colors. In the '85 I use a 50mBar regulator in place of the stock 30mBar, which increases the power to the fridge by 30% as I mentioned in a post 4 days ago. There is no change in sound; no roar at 50mBar.
