    I am totally new to this- having found the stove in his house after my partner passed away. Through research I know I have the older SVEA123 with the slanted valve. I prime the stove and it fires right up, but when I turn it up a flame appears where the key is used to adjust the flame. I assume there is a fuel leak there since the key will have a a little flame too when removed. I have tried letting it burn for a few minutes but that flame remains. I have tightened everything I can find with no change. Any suggestions?

    May have to add a little bit of graphite tape if tightening the jam nut on the valve stem/shaft did not help.

    There is one condition I have observed - the 123 uses a small diameter jet orifice. It occasionally may need to be cleared with the pricker tool, it doesn’t take much to cause trouble.

    A partial blockage or obstruction of the jet will increase the internal tank pressure and cause the condition you describe.

    Not saying this is what’s going on, but I’d definitely want to try this first, before performing any open stove surgery. Always try the easy or obvious stuff first, right? The stove will not operate at performance with even a partially blocked jet.

    Loosen, slightly, then tighten the nut on the spindle.

    Susan most likely may never return, leaving us wondering. She did mention tightening “everything I can find”. There isn’t much.

    I’m here! I took the nut all the way off and wiped the threads and put it back on and tightened it as much as I could. For the moment I don’t have an errant flame. I have ordered the “pricked tool” from EBay and hopefully that will make permanent fix. I live alone- electricity goes out fairly often and I needed something to boil water for coffee. This is just the coolest thing ever and I ALMOST tossed it having NO IDEA what it was until I utilized Google Lens.

    Susan, such an erudite and articulate person of good taste and refinement as you so obviously are, I shouldn’t doubt you have an acoustic guitar, amiright? Or you know someone at the very least.

    A cut length of light gauge high “E” guitar string is perfect & suitable for pricking the jet. My eyes aren’t the greatest, so I make it easier by removing the jet and running the wire through the bottom.

    If the stove already works well with a normal range of operation from a whisper to very high output, then an obstructed jet is probably not the source of the Unpleasantness. Since the stove is new to you, maybe you don’t know what to expect was my consideration pointing this out.

    But in any case, if you want to use the stove on the regular or not, a pricker tool of some sort is required sooner or later. Maybe not very often but if you do you’ll need it bad, it will be bricked (until it is pricked).

    Oh btw, you should post pictures! We like pictures of stoves & lanterns.

    What kind of coffee maker are you using with your Svea? I’ve been meaning to get a Bialetti.

    Alas, I played piano and never learned the acoustic guitar. However, it is helpful to know of an available substitute in case I never hear from the EBay guy again and don’t get said ordered pricked tool.
    Are you kidding with the coffee maker thing or there really such a thing?? If the electricity is off, I’m not above using boiling water and instant coffee to get my fix. I also can use boiling water and my Melina Ready Set Joe over mug pour through”brewer”.
    I recently went to my folks farm and scavenged some treasures to tinker with. With permission I took the Aladdin lamp that my mother never allowed anyone to touch (much less burn) and so far I’ve been through 2 $25 wicks and it’s still not quite right. Also found 3 old lanterns- a DIETZ D-Lite (broken shade and much too rusted to revive) and a couple Coleman’s from the 70’s in pretty good condition that I am trying to get burning.
    I want to get the SEVEA shining and then I will attempt to get a picture on here.
    I do appreciate an active forum!

    That looks perfect for the Svea. I take instant or freeze-dried now and then too, but it’s such a sad substitute. Right now I’ve Folgers, Folger’s Singles, a can of el-cheapo house brand, Bustelo, and some Starbuck’s Pike Place blend. I do my best not to run out, I’m not too picky, just need it to get my brain to boot up some mornings, and become ambulatory.

    (A 123R, but it’s the right coffee machine for any 123)

    @Susan M Underwood You can get an Aeropress coffee maker and use any pot to (almost) boil water, and it will make coffee that's about 1000% better than instant coffee.

    Yes, aeropress and SVEA 123
    I don’t like big brands coffee and I rather buy it from local toaster shop and fresh, would taste better.

    I used to buy beans in the green and roast ‘em myself. Shipping costs have gone up so much in recent years I can’t see how it would pencil out. The aroma is great, if you’ve neighbors nearby they will probably come begging.

    This is a whole new world. I was looking at the various machines to make coffee this way. I currently grind my beans with a standard little coffee grinder and make coffee with a standard drip coffee maker, but these are shiny and pretty so now I want one.

    You can sort of tell, this fella is not into DeCaff. They work well, Napoletana Caffetteira is a very old method to make the brew.

    Failing anything other than a canteen cup or a pot, it’s easy in a pinch to make Cowboy coffee. Bring cold water and coffee slowly to a boil, just long enough to “break” the grounds and foam. Let settle for a few minutes, and add a splash of cold water if desired to settle down any stragglers.
