You have to remove the jet orifice holder, very small barrel shaped pc. A clogged jet from burning cheap fuel is a hard one. first hold your lighter up and with only the air from your mouth blow as hard as you can straight into the lighter were the flame comes out, 95% of the time this will fix it. It is either dust bunnies or a clogged jet disk. Is there a way to fix this once it happens or is it just a byproduct of extreme heat? I usually cycle through that pattern 3 or more times back to back within a few minutes. Extinguish for 30 seconds or so then reignite for another 15-20 seconds, etc. Let's just say that the normal duty cycle of one of my torches is usually something like this -Ignite & lock on/keep lit for 15-20 seconds. I've come to think that this just be an unavoidable occurrence due to, umm, over use. I have minimal success by using a needle point and clearing all of the tiny holes around the nozzle and the nozzle itself but never seem to get it back to its original glory. After using for a while, sometimes after a few months, sometimes after a few days, the flame is much shorter, weaker, sloppy, and eventually will only burn a soft flame like a regular Bic when ignited. Here's the scenario - I buy a new torch lighter that's quick to ignite, has a strong, focused flame and couldn't be happier. I use torch lighters on a daily basis and have noticed a reoccurring issue that, thus far, I've had little to no success in both preventing or repairing so hopefully you or someone else reading can help. If there's any problem I have missed comment me and I'll add steps, to be honest I can't think of anything other than components going wrong after this. If the flame sputters and has trouble keeping going then it's too weak to stay above the nozzle, turn the gas flow up a little. If everything works but the lighter won't light or can't hold a flame turn down the gas flow a bit.
At this point I can't think of much else to go wrong, if the gas filler valve leaks when you fill it up then tighten it. take some thin wire or a pin and put it through the nozzle to clear it. If the gas still isn't getting out the nozzle then the nozzle's clogged, symptoms include the lighter bursting into flame for a second during use. Simply check where gas is going by pushing down on the lever for the gas valve on the reservoir, look carefully along the gas line, you should see something similar to 'heat wiggles' (from the change in desity between gas and air) if theres a leak, I you have a crappy BBQ lighter kicking around then cannibalize that for some gas line (there's enough for five or six replacements) and if you needed it they're a great source of igniters due to the extra long cable.
#ST DUPONT LIGHTERS WHY THEY NEED SPECIFIC REFILLS HOW TO#
All of these things are curable, this lighter hasn't many original parts, at one point I was going to hotrod a second nozzle in but There's no room, eventually I'll make an instructable about how to make your own jet lighter. This always happens if you set the lighter when it's hot because it starts easier but wont once it's cooled down again. try turning down the gas a bit (sometimes the gas can't ignite because it going too fast for the tiny arc to heat. Push down the button, is there gas coming out and is there a definite click from the spark (if yes to both this will be easy) If there's no gas coming out at the nozzle but it's going somewhere then the connection has been broken probably nothing more than the flexible gas line has slipped off the seat of the reservoir end (there's more room here so it fall off that end but it's easy to fix anyway) If you push the button all the way down and no click go to the shop and buy a really crappy cheap electric lighter, not a bic though, their piezios have no wire. Fill it with gas and listen, it may leak for a up to 30 seconds but that's ok as long as it stops. First put gas in the lighter, you should have done this already but this helps us determine alot.
