Hiya, I ended up buying another curious lantern, in Ebay, and when it arrived, it was real tiny but as far as I could see, "all there", but in a never been lit, state. Good news, you'd have thought ! On just making a check all round & a good polish up, I thought it wouldn't have been a problem, taking a light & then onwards, full storm ahead, but this certainly wasn't the case. The first lighting attempt (yes, I also ensured the generator was in good nic & firmly fixed in where it needed to be, even though it was a possible 80's lamp) failed miserably. There appeared a type of continual fuel drip feed, which circulated (all be it in a minimal presence) from the base of the genny nut lock, then up & around to this same locker. This area was certainly the culprit, for all the yellow flames (in excess, 10 inch high), flying up above the whole burner & beyond. So I first gave it all a good cleaning, which then brought my attention to the lovely new hoods enamel 'finish'; "My word", it'd been dulled out & was now damaged. The gloss sheen had been affected (centrally out), even though the flames were low tempered & yellow, & only at that, fizzling in this fashion, for a max of 5 minutes. A bit of a strange puzzle, why the temp's fouled it so but I've got used to it (better before though ). Caused by this experience, below :- Eventually, after advice from a far, I heard that it could be that either or all, the genny's flare needed honing down, to fit more flush with the valve generators seat; or failing that, there may be also some honing to be done, at the inner flip side, to the genny nut. Well, I quickly got to trying it all out, as my pal had leant me some grinding paste, he said they all used, to correctly re-seat, unused nuts & jointing fixments, within the Car Auto industries. Chemico/ fine grade, pictured below, turned out to be what the 'newness' (though quite old), needed badly ! Just orbitally encircling, with tube/ paste between all of the parts, with too much of a 'harris' on them, then allowed me to further tighten up the genny nut. It was as simple as that (most thankfully) as I'd not been looking forward to finding out it was something more serious. Phewwww !! Well well, the little pixie just lit up, straight off, & with no spillage or yellow flame detritus being ejected. I'd banged in only a small amount of fuel (just in case), then went to light, on twenty pumps; but it jumped almost instantly, to being a very bright mantle. It's not surprising that these little'uns, get so hot & its probably better there's not much fuel storage capacity. I can understand now, why those two 'O' rings need to be annually replaced (for when mine finally go 'kerpowh' !!) If any reader knows where I could source some tougher ones, please tip your hat, I do like this lantern, it is very portable, weight light, & up to press, very well behaved, so long as I keep remembering to clear the breach, every ten min's or so. Then alight !!! The shot might not look too bright a lumen glare, but it gives you colour patch's, if looked at too long. A good 'buy', it turned out; but I'd have been happier, if it could have been in the green Seafoam colouring, those are "very nice indeed, 'Mr Grimsdale" lanterns (he he & hey ho, for now). Cheers, Jon.
