Ron,
Oh, in the video, at first I used the stock burner then I used 3 copper pipe cap wadding burners. The surface area controls the heat level. The goal is a vigorous flame that doesn't touch the firebox. Reading about the spirit burners, wick selection (density) is very important. I personally think the Bing mushrooms are a bad design as there isn't a cup shape to it so over siphoning cannot be contained. I noticed that the Fleischmann that I am getting has a tiny cup shape to the mushroom and therefore must be safer.
