    image.jpg image.jpg Hi,

    I've inherited an Optimus 6 which is not in working order. I really want to get it functional again. The jet seems to be blocked, can I buy a new one somewhere? What fuel does it use? What should I use to clean it?

    thanks in advance for any advice provided.

    @Matt J

    That’s a grand little stove.

    This is not the same stove (below), but it will give you an idea of the various features.

    Your stove runs on Coleman fuel or equivalent. The jet in the nipple can be pricked with a high e string from an electric guitar (about 0.2mm)

    Svea 123 Disassembly

    Cheers

    Hiya Matt J,

    If you need some of the guitar E string, to prick the jet, let me know.

    I am a stove person, based in Christchurch.

    Cheers

    Thanks for the offer, I’ll see what I can do with the guitar string.

    Does anyone know if you can get a replacement jet for the optimus 6?

    Do you think there is a problem with yours?

    You can try Fogas.se; or The Base Camp (UK).

    A jet blocked by hard residues could often be pricked when it is heated to the point where the soot outside start to produce some smoke - then detach the nipple when it's still warm and clean out any residues inside - if the wick is still functional this would be enough to get your stove running again.

    I would think it is part 2502 from base camp Optimus Spares Price List

    But you only need a new jet if you are going to regularly use the stove. If you just want it to work clean the jet you have.

    Replacing the wick inside the stove is often worthwhile, but it looks like your stove does not have a nut to help you remove the burner from the tank. It you need to remove the burner assembly you could put it in your vice, between wood blocks, then turn the tank. The wick is cotton.

    Simon,

    Welcome Matt, I want to emphasize something if it is not apparent.

    You have inherited a rare nickel plated all brass stove
    (to say extremely rare is not overstating it but it is rare sure enough).

    Simon is a stove person.
    You're seeking advice, I suggest 2 things:
    accept any help/advice offered locally and
    consider not to attempt repair yourself just yet, if this is your 1st such repair.

    Brass parts that are seized or just real tight, is an unforgiving situation even for person with the experience.
    If you were to damage the vaporizer (center stem) or any parts, there is no turning back and no replacements available. Exception, you might be able to acquire a functional jet, as you are inquiring about. The filler cap may need attention (expect that) and like the entire stove.. is very easily damaged.
    -----------------------

    So what's the alternative… I believe Optimus 1st offered the 6 in the 30s. MANY years later, early 70s, Optimus offered the Optimus Svea 123. The 2 stoves are comparable in every way, except you need not be careful with the 123, it is replaceable and easily repairable. While you admire and contemplate your No.6, you can proceed with acquiring / fixing / using a Svea 123. <- excellent stove, not rare today and every part is readily available.

    Keeping the 6 on a shelf for now next to a user Svea 123 doesn't seem like much of an inconvenience.
    Like any collectible, retaining the "excellent original condition" of your No.6 will not hurt it's value (and it is irreplaceable).
    good luck
