Lighter won't light

[Emperor Zurg]

Scenario 1) Is the flame really low? Even when adjusted to the max? If so it's toast. Throw it away. There's a porous, plastic thing inside that functions as an orifice and filter for the butane. Eventually it plugs from filtering out impurities in the gas. All the purge stuff is nonsense, doesn't do a bit of good. Your only hope is to partly disassemble it and move the flow adjustment stop so that it allows you to adjust the flame higher. Not a fix but a bandaid that may buy you a little more life. To see if this is the problem, push the buttonn down and light your lighter with a match or another lighter. Tiny flame at max adjustment means plugged orifice filter thingy.

Scenario 2) The sparker isn't aligned right and it's sparking in a place in the air/fuel plume where there's either all fuel or all air. I had a cheap Ronson that did this. If you're lucky you'll be abke to bend the electrode around a little to some place where it's more in the air/fuel mix. Totally trial and error because you have no way of knowing the optimal position.
