When I started out, using a Prestolite torch, I lighted with a
candle for years. It worked fine for me. Of course, you have to just
barely crack the gas open, or the flame blows out. That goes for just
about any lighting situation. Now I use a regular striker with my
Little Torch. I guess it takes practice, as I can see from the
difficulty that my apprentice has with it. But she's getting better
with it every day!
If you ever have a problem lighting a torch, by any method, try
turning down the gas. That's probably your problem.
