A message to those who have used these classic bit of kit and can advise me on whether I should be concerrned, have an idea of how to 'fix' potentially or, where I can go to have it serviced (if there is such a thing).
We have a second-hand Coleman Dual Fuel 424 stove, which I've had since 2012 and used on several long holidays although not in recent years, other than an occasional outing in the garden when I needed a camping fix.
I found the 424 hard to pressurise myself, so relied on OH to do so but, as he's gone off the outdoor life, when I've been alone or with a friend, I've used the suitcase single burner.
However, for an extended family camp in July (to scatter my late sister's ashes - she loved a tent), I succeeded in using the 424 sans OH and felt very good indeed. My dodgy thumb didn't seem to hinder me as I'd feared.
Fuelled (!) by this success, I've tried the stove in the garden on days when I couldn't face being indoors to cook.
However, in use, I've noticed a very small amount of fuel on the top of the tank in the little hollow underneath the 'choke'/knob and connector to the generator.
Is this a normal thing (I can't remember if it did that in the past), or something to be concerned about?
If the latter, could something have coome loose and need tightening (if so which part ... )?
I've looked at some forums about restoring Coleman stoves but am confused about the names of the parts and even about whether there is graphite or other packing material in the joint between the generator and tank etc, and how to fix this.
Can any experienced 424 user advise?
The stove works fine other than this.
Many thanks,

At one time I had two of these stoves. One failed after many years of hard use and whilst I'm sure it could be repaired the thought of a tank of petrol and vapours not going where they should be saw me throw it away.
After 13 years it may be time for yours to go as any leakage of fuel isn't there by design. It is probably some of the seals on the pressurising plunger leachanism that have failed.
Is there a rubber washer at this location? Rubber perishes over time then may start to leak.
Locate and replace, there may be a plumbing supplier in town that has just the thing. Tell him what fuel you are using!
Don't know what had happened to my post yesterday!
It is not normal and it suggests there is a leak somewhere.
I would check if any of the moving parts are tight, starting with the generator, then the small lever, then the knob.
Good job the design has hardly changed since its launch, with many free to access information available via the internet.
I have not had any issue with my original 424 except to change the generator when the tip disintegrated.
I purchased a spare generator at the same time as getting a new 424 as I missed it so much after I sold mine when I changed unit from a tent to a van.
Good luck with finding and fixing the leak.

Thanks all, I did think it was not what it should be doing!
I will have a tinker with a spanner and have another peruse of YouTube etc.
They should in theory last for years and so convenient to take away.
I was toying with buying a new gas stove but might persevere with this.
I am ditching my Weber Go Anywhere BBQ to make room for the new Coleman 424, as I had not used the GA since I got my Cobb Premier Air which is sufficient for BBQing just for myself, whereas the GA is now too big and cumbersome.
I am meeting up with friends for my next trip and am planning to cook a nice Indian meal, and the 424 will come in handy. Need to take a spare table too for the stove though.

There is only three places it could be leaking from.
It could be from the preheating lever. Often a gentle tighten will fix it. The generator tube may be loose but that isn't common. They are notoriously difficult to get out and then the third place is the valve itself. A slight tightening may do it.
Rarely found but it could be fuel running down the generator tube if it isn't vapourising well or a blockage in the grey ushaped bit where the air and fuel mixes.
They are great when they work but a pain if something goes wrong.
