Reporting back on the lighter, not good. Negligible improvement so I’ll try a full repack with new cotton balls and a fresh zippo wick. It’s a large wick hole, maybe I need a different brand? IMCO, perhaps?
It's hard to say what went wrong without witnessing what you did. It's also possible there's a seam leak or some other exposure that's causing the fluid to evaporate faster. I've also had some spark wheels that simply don't make a good enough spark for anything but a sopping wet wick to catch.
Some people just try to fish a wick into the top opening and leave the packing the way it is. That will certainly lead to short flame results as the wick will only absorb fluid from the very top of the cotton packing. That's why it needs to go all the way through to the bottom.
Of course, you didn't do that, but that leads to another question. How much cotton did you stuff into that lighter? I've been shocked at how much cotton is in a lighter from the factory, particularly in some desktop lighters, like so much you'd never believe in a hundred years that much cotton could fit inside one of those things!
I jam it in there tight with a jeweler's screwdriver! I'd estimate a typical Ronson pocket lighter takes between 2-5 large cotton balls worth, depending on its size (they vary a lot) and something like a Ronson Crown table lighter might take 8-12 (I unroll them and pack them in a bit at a time from the flattened rolls and then use smaller bits when that won't go any farther). A Zippo by comparison probably only will take 1-2 cotton balls. I'm lucky to get a week or two out of them.
If you don't pack it in tight, it won't last long as that's all you have to store the fluid. Otherwise, it'll leak out or evaporate. Sometimes it leaks out big time anyway, but then I'm shocked how long it lasts after it stops.
There are, of course O-ring seals available for the screw caps for fuel and you used to be able to get sealed wicks from Ronson, but not anymore.
Of course, if the lighter insert is very small, it probably won't last too long regardless. Two days is bad, though. I'd expect 4-5 days even from smaller wick lighters (the smallest as 8n tiny might last only a day or two).
I've had a few table lighters light after 6 months or more. My Touch-Tip I used lasted probably two months on a half fill, but it takes a lot of fluid. It nerds a good seal around the wand, though or it'll evaporate fairly quickly.
I've never used Zippo wire wicks, although a couple of lighters had them in already (including new Zippos, of course) so I don't know if that affects it or not. I buy IMCO brand needle wicks off eBay. They have a needle threaded on already to make insertion easier, but can be clipped off if it doesn't fit for some reason. I also have an assortment of different sized cotton wicks from a guy in the UK. In fact, he usually includes a pack as a free extra if I buy a few valves or other parts from him, but he also sells them.
I've had a few lighters that needed smaller or larger wicks and drilled out the Youngstown made Firefly lighter to take an IMCO as it was too small an opening and the smaller wick worked poorly and didn't last more than a couple of days. I'm not sure the wick was wicking up the fluid fast enough to stay lit after that. The larger IMCO wick works great in it, but I did have to drill it out to a larger opening first like I said.
