I test fired my newly purchased 249 tonight and after a few burps, farts and flare ups it started to run well but once hot the control wheel gets really stiff and is difficult to turn but is fine when cold, its not leaking from there but the nut is fully tightened so i guess the valve packing has compressed significantly, i've got some graphite tape that i can use but i cannot remove the valve stem, the nut is undone and the stem is unscrewed it just won't come out and i don't want to force it, am i missing something?
Thanks.

I managed to remove the valve stem with quite a bit of force, the packing looked ok so i cleaned the threads etc, reassembled and it is better in use now so turned it off and left it under pressure overnight but woke up to find it has leaked fuel from somewhere, probably the jet, not sure if its something i've done or if it already had a leak, i did clean out any loose graphite that i could see and used a pipe cleaner to try and pick up anything from further in, the lantern does shut off by closing the valve, maybe it is not quite closing fully though?

Hi , sorry you had to answer your own post😉, sounds as though the valve maybe not seating all the way or the taper on the end is worn possibly?
If you could strip it out and post up some pictures it would help, to confirm where the leak is you could empty the fuel out and do a dunk test with the tank pressurized,  (look for air bubbles)

Thanks Tony, i dunk test all my lamps etc (normally after replacing all the seals) before lighting to be on the safe side and this one passed with flying colours, it looks to be lowish use and there is no wear or groove on the taper and i couldn't see anything on the seat but that doesn't mean much as its difficult to get a good look inside, i disassembled it again and used some thinner pipe cleaners, which is all i had, to try and clear and debris, refitted it and it has been closed and under pressure, fully fuelled for a couple of hours now with no leaks, i will leave it all day then put it back together later and run it again for an hour or so, turn it off and leave it over night to see how it does, it was left on a piece of mdf and although the fuel stain was around 8 inches by 5 inches its probably not that much fuel, hopefully the problem has been fixed.

So it still leaks (from the valve stem nut) when turned off from hot although passes the dunk test or doesn't leak when tested from cold and if i tighten the the nut more when leaking it stops but once hot again the knob is then difficult to turn, the graphite packing still looks in good condition and a decent length bar a small piece that came away because i have removed the stem twice, is there any way to rejuvenate the original packing or does it need replacing? i have only got graphite sheet or tape here at the moment.

You're sure it's the valve leaking? It probably is, but I found that with Coleman kerosene lanterns when you shut them off the same way as a Coleman CF lantern I would always get a leak of kero from somewhere overnight. It turned out to be the remaining kero in the valve (above the shut off) and the generator that would expand at some point and seep out of the generator tip and down below the frame. Worse with a 237 or 249 than a 201 or 247 due to more fuel in the plumbing I expect. Just a small amount creates a big mess.
To stop this, I never turn them off with the valve wheel, but vent the fount by opening the filler cap. Then I leave the valve open, and cap loose, when storing. Much like the euro-keros.

Yes definitely from the valve stem nut, i stripped the lantern down again whilst still leaking, wiped off all of the leaked Paraffin, tightened the nut and left it another couple of hours and the leak stopped, there was no sign of leakage from the generator tip or down its length.
