Advice sought re. located Optimus No.96 pressure leak

[Silverclaws2]

And so it has come to pass, perhaps as part of that midlife crisis that I have obtained the very variant of the Optimus No.96 that I used on my Queeen's Scout Expedition back in 1986 and in ' Fettlin ', I discover it has an air leak giving rise to inability to hold a burn of which hardly useful as I am not intending to retain this stove as a mere ornament.

To have by way of the submersion test found the air bleed screw on the filler cap isn't sealing of which is hardly drastic but I would be interested in receiving advice upon options before I plumb for a generic replacement.

Dunno, with experience of these stoves I get the sense that the bleed screw is an incorrect screw as it is overly long for it's purpose of which is not something I remember and of course the cone appears to be in seach of a deeper seating of which is not something my No.96 has

There are certainly knowledgeable folk here who may be able to help you. (Not me I’m afraid - I have an aversion to moving parts.)

Otherwise may I recommend
Classic Camp Stoves where questions like yours are dealt with every day.

Edited to add:
They will be able to tell you, within microns, what you need and where to get it.

They are great people. I’ve dealt with them on line as a very ignorant rookie and they have helped me out. I’ve even met some of them at their camp.

Have you tried wrapping some ptfe tape around the screw thread? It could be either worn thread or some dirt in the thread, I don’t believe there is a gasket that goes in there as far as I can remember but I’ll check one of my stoves later. Or possibly the clever use of a fibre washer? Hmmm

As above classic camp stoves is the place to visit.
Make sure that the threads are clean as a bit of debris could be enough to allow a leak.

SOLVED.


I am to mark this thread as solved as I have discerned and curred the problem

The problem was that the air bleed screw was the wrong screw for the fitment, but with the poor man's lathe (drill) I ground a new angle on the bleed screw cone and with the use of autosol and plenty of to'ing and fro'ing I managed to grind both faces to the point they would seal hence solving my problem.

An extended burn last night revealed the mini camper could boil a pint of water in just under five minutes, it will also perform quite a respectable simmer and yes despite the stove not being specifieds as auto start stove, it will auto start of which is what I remember of my original No.96, to conclude now with the leak cured the stove is in fine and dependable fettle.

I would post an image of it in full roar, but I have no idea how to do so here
