    Sportsmansguide.com had what was an apparently very limited quantity of 'surplus' 111's. Luckily I spotted the ad quickly and picked up one for $79. I wasn't too sure about the condition so I only bought one. Wish I took another before they sold out. 111's at a good price are very hard to find.

    Since this is my first 111 (I have one 111b) I would appreciate any tips or tricks on using this stove. I did have some new parts for my 111b that I used in this 111 (new spindle, cleaning needle, packing). The tank cap needed a new pip as well, and I cleaned the case and tank up a bit with some polishing compound.

    I'm guessing that in its currently configuration it will burn Coleman fuel fine but what is needed to burn kero or alcohol in these?

    First off, do you have o-ring or leather pump cup.
    It truly dosn't matter. Some like leather better.
    The o-ring works fine. As for fuel, the 111T, in the picture, was designed to run on kerosene. But it is a true triple fuel stove. Ony change is the jet.
    Range of Jet Sizes Used for Optimus 206/207B burner
    ±.02mm(.0008") wo/noticable change
    Alcohol 0.51mm(.020")/no air restrictor #2508
    isopropane 0.45mm(.018")
    White Gas 0.37mm(.015") #2510
    Kerosene 0.28mm(.011") #2500/#2509
    Mjet-k/wg=0.032mm(.013") #2502/#2509
    Mjet-alcohol=. 032mm(.013")+air restrictor #2502/#2509

    The 111t has the optimus #206 burner.
    most all surplus 111t's seem to have the "M" jet installed. So conversion to from Coleman's to kerosene is just empty tank, and refill with kerosene. Some surplus stoves hade "A" jet installed. Equals to much fuel=yellow flame tips.
    Don.t mix the fuels. Empty tank completly than refill. If you have good flame w/Coleman's fuel than you will have great(hotter)flame w/kerosene.

    I do have what I would consider too much yellow flame and I'm not satisfied with that. I think I have an extra 111B nozzle that I can fit on there to check its performance with Coleman fuel.

    Thank you for the reply and information.

    I tried a couple of different jets that I had laying around. All were from older stoves so I was unsure of their actual condition, but I finally found one that gives a fairly decent flame with Coleman fuel. Still a little bit yellow, though. Tomorrow I'll try kero with the same jet and see if it works any better.

    I have the multifuel jet in mine, & burn either kerosene or coleman fuel. It works very well with both, but i prefer coleman fuel as I am already carrying it for my lantern. I also find kerosene fumes get pretty thick in a small cabin or wall tent. Brian.

    Being mil surplus it was probably set up for diesel. I nabbed one of these for the kap arctic quest (update imminent) Mine was missing parts from the stuffing box but Gary AKA berniedawg really came through with some much needed bits. The burner is running well now. Mine had a couple of of ounces of diesel or kerosene inside when it arrived.

    I own two of only one type of stove: the 111. I have a T and a B. While I love the roarer burner in the B, the T is just a delight to burn. Yeah, kero ought to be a controlled substance!

    Question on the 111T burner. You said it is the 206 but basecamp shows it as the 221. what is the difference between the two and does it matter

    Haven't yet been able to get a satisfactory flame pattern out the 111. Still far too much yellow flame with Coleman fuel, and kero is not vaporizing even with substantial preheating. I still have a couple of other jets to try but not sure of the actual jet sizes that I'm trying.

    I did completely disassemble the stove and cleaned it thoroughly so that's not the problem. At this point I think it's just the jet. I'd really like to get this running well on kero.

    Try the jet from a 8r or svea 123 if you have one. Should be the same as the m jet.

    Also your photo does not show a restrictor, if the stove came with one it may be in place now. If so remove it for use with the kero and m jet. It is a small steel pipe under the burner cap that goes down to the jet.It is probably not there, don't worry if its not.

    I finally got the 111 running perfect with a new burner cap. My only question now is how to actually attach the cap. The original had two tabs and screws to hold it in place - the replacement has no visible means of attachment to the burner. What am I missing here?

    There are burner heads with the tabs that hold the cap in place, but with others it just sits on the burner.

    You could fixn the cap in place with a steel wire.

    Hi, as ajvuik suggests, just use a piece of steel wire to hold the outer cap in place.
    Pass the wire over the top of the cap, thread the two ends through the nearest holes in the burner skirt, and bend them over.
    Best Regards,
    Kerophile.

    Thanks for the help. This is my first 111 triple fuel and I'm amazed at how fantastic these are when running properly. I'll try some kero in it later and maybe post a pic or two. Now back to the search for more of 'em.

    I seem to get better simmering capability with Coleman fuel (no yellow flame at all) as compared to Kero. Anything above a low simmer, though seems great. I plan on sticking with the Kero in the 111.
