    I own an Optimus No 96 stove bought in Edinburgh in the mid 80s.
    I'm looking for repair, maintenance & spare parts know-how in the Cape Town area.
    - PLEASE MAKE CONTACT if you can HELP OUT, see below

    The stove has been unfailing untill recently - a real old faithful - but now it won't maintain pressure.
    - now it lights OK but pressure fades within a minute of being pumped up
    - & will go out if left

    I've googled & found some likely answers but would appreciate local knowledge & info on tools, spare parts, etc.

    Most likely problem is pressure loss at?
    - filler cap? - need new seal washer
    - pump's non return valve - need removal tool & spares

    - PLEASE MAKE CONTACT if you can HELP OUT with this

    look forward to hearing from you - Fraser

    Thanks Haggis - with that 'nicname' you must be in Scotland ... right? My home country.
    - its good to see these forums work :thumbup:
    - Fettle box looks like a useful supplier.
    - if can't find help locally (in Cape Town) I'll use them

    Thanks again - Fraser

    So I see from your profile page @Haggis - you must have Scots roots then?

    Yes,,, @OptimistCT,,, both sides of the family, with mother’s family arriving here not so long before I was born,,, Barra MacNeils.

    Truth be though, the Barra MacNeil clan traces its DNA roots to viking ancestors. A fella tends to run back through his history, find something he likes, and settle there,,, a quirk of human nature I suppose. Guess I’m more romantically inclined towards bagpipes and single-malt than battle axes and mead...

    Had a friend from the Isle of Lewis, a piper I played with in the Scottish Rite, a recent “American”, and he often mentioned that whilst being a native born Scot, his family roots were Nordic ...

    So I goes...

    There of course is a large strain of Nordic in Scotland, as in Ireland and the North of England; obviously because of the Vikings. Often overlooked, what with the stirring tales of marauding, seagoing Northmen and all, is that Vikings settled in the British Isles in large numbers, farming and inhabiting the lands for generations.

    Accordingly, place and family names in the North of England are replete with old Norse derivation. My own family name, from a small hamlet near Penrith in Cumbria, is Old Norse. "Shelter from the wind"; in short, wind-shield. Probably a spot where Viking farmers and drovers took shelter now and then.

    Probably dates from the 9th Century or so. There's nothing so English as an Old Norse name!

    20201010_130958.jpg 20201010_130938.jpg 20201010_130103.jpg YEESSS! - it WAS the filler cap seal (old & worn) causing the pressure loss.
    My local fix worked - stove now working again - YE-HA! :thumbup::thumbup::thumbup:

    - Manufacured a new seal washer from a silicon rubber baking mould - fairy cake size - supplied by my wife. S-Rubber 1mm thick.
    - marked out with old school dividers & cut with a stanley knife - new blade.
    - put in ontop of the old washer
    - can pump up to full pressure ... & it holds

    So, no need to order in from the UK ... this time - but good to know about Fettlebox.

    Putting this one down to native Scots ingenuity ... & modesty :-({|= ... playing my own fiddle :lol:

    BUT ... pls LET ME KNOW of any problems, etc you may see with this - haven't used it for real yet.

    PS ... admire your Scots heritage knowledge ... best I can claim is that my Gran grew up in Stirling Castle where her Dad was stationed as a soldier ... but surmame O'Connel :?

    @OptimistCT

    You can check how well that silicon washer withstands kerosene by dropping some of your leftovers in a jar of kero.

    Cheers

    Hi again Tony & ALL, a QUESTION - is your post passing on definite knowledge
    - ie. you know SR WILL degrade in contact with Parafin (Kerosene)
    - OR is it just advising to check that it MAY do so

    - I have googled a bit but can't find anything defenite.

    - I thought your suggested test sensible - & soaked overnight.
    - the soaked silicon rubber pieces seem a bit more 'brittle' - easier to puncrure with a screw-driver - than not soaked SR.

    Am experimenting & would value any definite knowledge you have - tx - Fraser

    Ersatz fuel cap seals cut from the side of say, a 5 Ltr polythene paraffin jug, work well and last a long time. Suitably sized bits of pipe with the edges sharpened make good punches for cutting them out.
