My grandfather passed recently and he had a bunch of different lighters, mostly regular ones and a couple of the cheap torch ones that my dad took for work, but I really liked this one so my mum let me have it. I've done some searching and it honestly just seems to be an Amazon knock off of some other brand but that's okay. I'm trying to figure out what the screw circled in red on the bottom is for and I'm not getting answers.
Everything keeps saying it's either the refill valve or the flame adjustment, which is the black circle and the hole inside of it. I'm unsure if the circled screw is needed for anything but I dont want to take it apart and risk messing anything up just to figure it out.
And before anyone says it's for the clock on the front, it's not. There's an unpictured screw on the side to take the clock off to change out the battery for it.
Any help would be great, this has been bugging me for almost two weeks 😅
