Before you decide your stove is the culprit, look at the surface that you have below it. If you have a cold tile surface, cold concrete, whatever, then your stove is sitting on a giant heat sink.

Find a piece of cardboard roughly the size of your pot and wrap it in aluminum foil. Get another piece of foil a bit larger than your stove and bend the edges up to form a small lip. Put the stove on the lipped foil and place both on the wrapped cardboard. Put fuel in the stove and several drops on thet lipped foil. With the windscteen in place and the pot ready to go, light the alcohol in the lipped foil. Let the flame pre-warm your stove, then, if necessary, light the stove, placing the pot and stand over the flame.

If your stove still doesn't work, maybe it is the stove, but try it with different amounts of alcohol before tossing it.
