    Is there anyone who would be willing to take on the task of cleaning my King of Stoves - the Svea 106 - to help me achieve the sought-after blue flame?

    Some of you may remember my posting about this back in 2008: Orange-tipped flames

    I have tried shaking things around the tank with Kerosene, and I have tried spraying the tubes with carb cleaner. I even installed a clean new jet. However, the flames are still yellowish-tipped to the extent that my poor pan bottoms are getting sooty. And I can't have that.

    Is my desire to have someone actually help me against the classic camp stove rules? Am I supposed to fettle into my old age and enjoy the journey, regardless of whether I accomplish my goal? Fellows, you must at least credit me the courage to ask for help!

    Here is how he was when I got him:

    And here is how he appears now after I cleaned his outsides:

    And ready for tea:

    I live in Vermont (USA) and would be willing to pay for round-trip postage to your home. Anyone interested for the sake of the challenge or for a small pittance? Perhaps there's someone out there with an ultrasonic cleaner? Or perhaps more patience than I have. I only ask that if you get the blue flame, that you share your secret.

    Hi

    You might need a new nipple (well, actually not you but the stove).

    Before you do so, you might try de-coking the burner.

    HERE is me cleaning an old burner - remove the nipple first.

    Thanks for the ideas.
    I haven't delved into the realms of soaking the stove in chemicals and heating/quenching to loosen deposits.

    What I did do was install a brand new jet/nipple. No improvement, infortunately.

    I also put a fresh washer below the cup.

    The system seems airtight, in that it pumps up well and the gasket on the cap seems to be making a good seal, but who knows...

    As I indicated above, your burner may have thick carbon deposits.

    Thanks. I'll explore options regarding coaxing out those possible deposits... !

    Beautifull stove Griz. Do you have the right sized jet installed? What about the quality of your kerosene? I have had kerosene that smelt strongly of diesel and burnt similar flames to what you are getting from your stove now, sooting the burner and pots. The fumes were nauseous as well.
    I changed to a known better quality kerosene and the problem was cured. Initially I thought that my jet size was incorrect.
    Cheers

    Another possibility could be that the jet(nipple) hasn't got a good seal in its seat.
    I usually lightly coat the thread of the nipple with graphite paste and insert it firmly but not too tightly so that when the oily residue is burnt off, the harder graphite that remains, helps create a better seal. The nipple will be easier to remove in the future helping to protect the thread in the burner as well.
    Cheers

    I recently moved from Inverness to VT, but my heart is still in Inverness!

    Many thanks for the offer to do the heating method for loosening deposits. I will try other options first and if I don't make headway, I'll sent you a PM.

    As for the Jet -- it was sold to me by A&H, Part #2500. It fits and sure looks like the original jet that came with the stove. Do you think I'd be better off with a different part number?

    As for the kerosene, it was from a fresh can, so I suspect it isn't the culprit.

    I will try the graphite and the snugging of the nipple. In general, I don't have the sense that it is very snug.

    As for the beauty -- yes, he is lovely, and for those who appreciate such things, there is one perfect little ding on a part of the tank.

    Thank you all for your suggestions so far. I welcome any more, such as whether Ultrasonic cleaning would be a waste of time or not.

    Some place in the fettleing section i show a Phoebus #30 stove with a really coked up fount (tank). It is possible your stove also has such a problem which would affect the operation if that coke were to get into the fuel.

    Ultrasonic cleaning is always an option to cleaning out any kind of residue in your stove or a watch or any other object which requires cleaning. It would not be my first choice but i'd certainly consider it if i had no others.

    Hey, Griz,

    Jet #2500 is the proper jet for Optimus (and probably Primus) 00/210,1,5,45,48,100. So, it should work just fine in your stove. I'm thinking that, as has been mentioned, your burner if coked up (very likely), or your tank has some residue inside it. Either way, Lance can take care of that for you, as he has so kindly offered to do. I can vouch for his absolute honesty and his undoubted capability, as will the many others that know him here at CCS. Take care, and God Bless!

    Every Good Wish,
    Doc

    Thanks for the confirmation of the jet and the vouching for member Lance. I will graciously accept that help after I have fiddled just a little more.
