The fiberglass wads only hold a flame for about 25 seconds (WAG) which is long enough to heat the fuel in the stove to a point where it exits under pressure and "contribute" a flame to the pressurized fuel.
What I like about the stove design is that it does not need mesh, or fiberglass to burn. Originally, I would dribble fuel down the sides of the can and light it with the fill hole uncovered, then tried to throw the coin on, which if you have ever played tiddly winks, hardly ends up covering the fill hole.
I would highly recommend you try the pressurized Pop can stove. I used a dictionary, a box cutter, and a Dremmil with a thin drill bit, and needle nose pliers. Cheap and easy.
