Sometimes there is too much air in there....other times just a little adjustment works. Turn the torch all the way down. Click to see no flame. Turn the torch up in 1/8-1/4 turns checking for fire all the time. Eventually, it should fire. If not,try getting some compressed air and blowing it out (just like a keyboard). If that doesn't work; turn it over, push the fuel outlet, and drain out all the fuel. After it is empty, keep pushing the button until it quits hissing. This burping process clears the fuel chamber for pure fuel. Those quick fixes usually work.
