The burner that comes with the kit is a chimney style burner and according to the litrature that came with it has been researched to be the best design of stove for the oxygen-starved cone set-up. I can see why, it produces a fierce central flame which hits the middle of the base of the mug/pot and then spreads around and slightly up the sides. The side jet pop-can burners seem to direct heat to the sides of the pot rather than under the base, even with a 700ml wide based ti-mug.
But, I trod on the original burner that came with the kit
It's still made from a red-bull and standard 330ml pop-can but also has a large aluminium base that I can't recognise. Unfortunately it's quite fragile and they cost a whopping £10 to replace so I set-to making my own.The outer sleeve is a beer can, base is a Kitikat tin base and the central inner pot is an aluminium aerosol pot that had to be selected to be the exact size to slot into the inner ring of the beer can. This means it's a few grams heavier than the original, but far stronger. Although it's twin wall, the meths stays in the central pot. The holes are simply to allow air to be drawn through, there is no priming required.
Being designed to be used in conjunction with a cone it obviously has to be used with a pot support, you can't put your pan directly on the burner.
I've been using it now for a couple of weeks and it's been great, I even treated it to a lick of paint! It seems to burn slightly longer than the original, so I suspect I could open the vents up a little to create an even stronger flame for a quicker boil.
If anyone is interested I'll pop up some manufacture drawings.
Reckon they'd be fantastic mated up to a cone clone.
