Second thing is to carefully prise off the chromed metal surround from the front of the lighter and relocate the flame adjuster lever on its valve so that you can get a decent length of flame.
The lever is usually fitted to the valve by a splined ring, which the lever is protruding out of. Just lift it up off the splines of the valve and rotate a couple of teeth or so, then push it back on. Press the surround back on after doing this.
All the lighters sold here now are supposed to have child locks and very small flames, usually only about 1/4"-3/8" high, if that. Enough for lighting a cigarette, but useless for lighting a fire or anything else. I am a pipe smoker and they don't work worth a
