I have made dozens of stoves of several designs, none of them have been as efficient as the one that comes with that kit. By that I mean that I can get a faster boil but use a lot more fuel (about 1/3rd) or use less fuel but take about twice as long to boil.
Ax much as you like tinkering, I would leave this one alone.
Well, I did make a gas conversion...(works very well...)
