Greetings, All, @snwcmpr wrote: "Where are we getting this model designation with dashes? MF-1?? There is no such model." I am 100% in agreement about this extraneous, hypothetical naming of MSR stove models! This is absolute conjecture on the parts of those to go down this path, and it is doing the Stove Community, overall, a huge disservice, by creating confusion, where NONE existed before! MSR named their stoves, and the names that MSR gave them are the ONLY names that we should be using to discuss them. To do otherwise is to confuse, and mislead those who come here for concrete information!! Certain Models, at some time, transitioned into other Models, and the names are clear. Let us, please stick to factual information, and leave the conjecture for other things. Take care, and God Bless! Every Good Wish, Doc
re my: "There have been well-intentioned stovies invested in the topic that were discouraged here along the way : ( . There are conflicted accounts and inaccuracies." ...and... here we go again : (. If there are clear on-point specific corrections (with links to back it up) to the topic, that would be different. i stand by all of the above. @mojo please do not be deterred or discouraged. You and I have no troubles. There are at times comments that do nothing to contribute to collaborative progress in reference section. it happens. ----------------- mojo, this Q&A now very much fills-in the MF burner details. Perfect It is not all explained in 1 place (not yet) but some missing details are finally confirmed. "I think" we can call MF details done. This has been many years and many members. Today mojo wears the hero hat for filling in the last details for the MF versions (i thought, eventually, it was going to be Duane). Collaboration is key. THANK YOU mojo @hikerduane there are tidbits that may be of interest a bit of a recap, separate details in no order: all, With too many stoves and many years of emerging details and collaborative efforts (on & off) there has been significant progress made. Duane not always into details and not one for lengthy explanation but for key details his accurate input has enlightened this topic as much as anyone (other topics too, same way), we could not get this far w/o him , and others. Collaboration is key. Duane re mojo's "MF-2 The jet is strongly tightened and cannot be removed." ah ha, you can maybe relate to that. re ^^^ that was open question to Duane re his early MF. We're all good. mojo has answered it, that one is DONE. @mojo "your MF-1" an early MF (MF w/solid helix) narrows age range, that one is Jun/Jul 75 -to- before May 76. fwiw early (earliest/ver 1) MF details eg [earliest MF example] Unfired MSR MF continued scalloped burner detail and shipped with the all yellow pump. Mass production (assembly line) MSR stoves are assigned a model designation. There will be times it will be difficult (impossible?) to conclusively assign a used MSR stove it's model designation if it is no longer "original or it's minus labels / packaging / paperwork). ================ EDIT for Duane's comment just below vvv again, good man, "Duane ... We're all good." you HAVE BEEN very helpful over the years.
Sorry, I can't help much, harder to keep track of details, small changes, recall stuff, reason, even use a calculator more for some math. My skull operation was no help, Doc said I would never be the same. Duane
There is no MF-1 stove. So there is no facts that can substantiate the naming convention except for something that you made up.
@snwcmpr "There is no MF-1 stove." we agree and i never said or implied there was one, in-context. in my view this is your own, self-made, "MF-1" distraction, you got confused, others too maybe. PLEASE all, refer comments re this "MF-1" confusion / distraction to the lounge, where, as you know, it has already been addressed. in Random Thread specifically here link prev in this thread also, ALREADY asked and answered in-context Q "Where are we getiing this model designation with dashes?" A "I think OMC probably numbered them after seeing the photo I posted. I know it's not numbered." ... remember he does not speak english aka numbered them referring to the photo I posted. ===================== ===================== members wanting to identify specific details re an MF model (or possible MF model), earliest known MF early MFs later MFs last MF ... the accurate details are now here. This, once again, despite the inaccuracies, the distractions and knocker n mockers. again, mojo and others, please do not be deterred, carry-on, on-topic. thanks to all, well almost all.
@snwcmpr All the "-1" etc refer to the photographs of the stoves, left to right. MF-1 is the leftmost stove, DF-2 the rightmost. It is a notation that only applies to stoves in @mojo's post below.
this continued to go off the rails in reference section, despite CLEAR exit ramp link provided (take bitchin to the lounge). Nice to hear from scrambler, not confused by the comments. mojo's lineup, the context, btw I take comfort aware of the many smart members who see various bloviating for what it is. We are all being distracted, which is a sad state. i said my piece. Sorry for repeating myself but to be clear, still, PLEASE all, refer comments re this "MF-1" confusion / distraction to the lounge, where, as you (snwcmper knew) know, it has already been addressed. in Random Thread specifically here link ====================== It will be sooo much more useful/productive to move on, on-topic, to the DFs . DF or early GK that is the open question. mojo and all those interested in advancing the DF or early GK question, Please do not be deterred, please carry-on. i gotta run but will follow with interest.
@mojo, Your stove is a Model G/K! Not a DF or MF. What makes a Model G or G/K? Unmarked jet is shared between the G & G/K stoves G & G/K jet is larger and will not fit in the Model 9A, MF or DF burner Flexible removable cable to clean out any deposits in the fuel tube The Model 9 original sparker unit is swapped out for the later Model 9, 9MF, 9A, MF & DF sparker units The Model G & G/K stoves were manufactured in August 1977. e.g., New MSR Field Maintainable Stove instructions. MSR made separate jets for Model G & G/K stoves, c. 1979. The first mention of separate marked G & K jets is 1980. Model G & G/K stoves were replaced by Model X-GK on November 2, 1981. The stove in the link below is not a DF it’s a G/K. MSR Dual Fuel Stove Some members here believe this to be a DF based on the instruction sheet. MSR didn’t have time to create an instruction sheet for a new stove they wanted to launch so they included the DF instructions. Notice the box reads G/K. The first Model X-GK, November 2, 1981, shipped with G/K instructions. You can see that the stove, MSR Dual Fuel Stove, shares the same fuel tube, filler cable, unmarked jet & sparker unit as your Model G/K.
Stating the obvious mojo relies on online translator for all of this. @mojo you have done well with all your comments, keep up the good work. it will be good if you rejoin your thread here, please. i thank you either way. re open question in your title: is that stove a DF or GK? I join thanks to @oddball for his answer: "Your stove is a Model G/K! Not a DF or MF. " I'm not disagreeing, it could be said i tend to agree. I was surprised he too saw your flat top gen and answered plainly, it is G/K? My latest answer from above does differ slightly, I do not (yet) answer with the same certainty: "What I see looks to be a match to an early GK. *Caveat: confirming late/last DF would shed new light on this." ------------- Thank you oddball for all the other details in your comment, as hobby time allows, it will be interesting/enlightening to compare that to what myself and others have found to date. ================= fwiw, 1. oddball is helpful here and provided details , i am definitely thankful for that but, in-fairness i want to also add that, for me, a. the same late DF *caveat applies vs statement saying that the 2015 posted MSR Dual Fuel Stove is not a DF. We consider what is posted there, a peculiar combination AND left with unanswered questions, including b. Posted as a DF... maybe it is, maybe it is not? -------------------------- DF details have been especially elusive. I join the efforts, I am thankful for any/all efforts towards confirming DF details. I have shared my suggestion on defining a DF and still seeking more confirmation, myself. We are getting closer. "Now [2023 Mar.] with MF details confirmed (1st ver to last ver.) , and with *early GK info, with process of elimination defining the DF has got to be as close as it has ever been. ... ...*the revelation there being, rare early GK still has wire wrapped flat top gen . Confirming the late/last ver. of DF ... " [ yet TBD, from what i've seen to-date ]
Hi everyone, you have given me a lot of explanations. I am very grateful to all of you. Can I see the definitive DF proof photo? I have no doubts. I just want to know. I would also like to thank @OMC again. He was very supportive to me as well.
From MF to GK, how many types of stoves are there? So is this late MF? Or is it DF? I want to see a decisive DF. Thank you.
@mojo re your: "I want to see a decisive DF." join the club : ) . There are DFs (w/paper labels) out there in-circulation. It's seems odd no more have surfaced and no one is sharing details of such a find? Every month that passes increases the chance that any paper DF label out there will fall off. There are "DF"s posted but for whatever reason, posts are not conclusive and questions re details go unanswered. re your: "So is this late MF? Or is it DF?" That is a good question. You do have good questions and comments FWIW my position Mar 2019: The last known version of MF, it seems even more likely now, is identical to the 1st version of DF. We've known, June 76 DF (&MF) instructions refer to "...helix ... removed ... or hooking hole in helix with wire..." [ an aside, so far, all burners with helix have early small burner that is threaded to the top (not wide top) ] >> caveat (challenge), MSR has on occasion distributed paper that is conflicted or in error. "ON paper" the 1st DF did have "hole in helix". This is where i remain (last MF & 1st DF=same) given what we've seen.... Of course, lots of things look good "on paper" that in reality are not so (all things not just MSR). Sad news, if we pater confirm track record that the last MF & 1st DF are identical... who is to say the last DF and 1st GK are not the same...? aw geez. don't blame me i'm just the messenger. Sorry this is long (difficult translation) and sorry i am not more concise. In my defense DF details are complicated to attempt to sort thru. and i do strive to be accurate. cc @oddball cc @Scrambler i am hoping you follow what you can as your time allows. I am out of time, no where near ample time in this week to handle an increasing workload (worked til 11P last night on "day off"). Will catch up when i can.
@mojo re your "From MF to GK, how many types of stoves are there?" i will rephrase your question From MF to first/early G/K, how many types of stoves are there? (there are different versions of G/K). Now, with your help, as far as i know we can answer re MFs. MFs, the first is quite different, it is rare. It is an MF version, we might set aside as it does not compare (closely) to all other MFs. That leaves the next, more common, 2 (or 3) MFs: early MF (not the first, that is unique unto itself) late/last MF (defining first/early DF will shed light on this) i wish i had more carry-on
@mojo @OMC One! The Model DF, which happens to be the Model MF. The stove in the photos you posted could be an MF or DF because they’re the same stove. Read on! Here is a decisive Model DF. MSR makes FIRE The Model MF and DF are the same stove using the same jet and helix coil. There is no difference between these stoves other than the fuel recommendations in the instruction manuals. Model MF recommended fuels: Coleman, Chevron Blazo Fuel, Kerosene, Jet Fuel, Stove Oil or Stoddard Solvent. Model DF recommended fuels: Coleman, Chevron Blazo Fuel or Kerosene. There were probably too many complaints about the Model MF clogging from the Jet Fuel, Stove Oil and Stoddard Solvent. The easy solution would be to rename the stove Model DF (Dual Fuel) and remove the Jet Fuel, Stove Oil and Stoddard Solvent from the Model MF (Multifuel) stove instructions, which they did. The MF and DF instructions have the same date, June 1976. Yet the Model DF does not make an appearance in the Newsletters until March 1977. Shown here are the MF and DF instructions that appear to be identical except for the description of the fuels.
i am onboard last MF & first DF are same (rod in fuel line for one). re this DF "Here is a decisive Model DF. MSR makes FIRE " fwiw that is the only "DF" labeled stove i recall myself to date. i am curious if there is some confirmation we can reference, someone/somehow/somewhere that, that DF or a DF has a rod (not cable) in fuel line?... it would be news to me (as in myself i just do not know either way), and it would be nice to put it to rest.
@oddball I am not saying there is more than 1 version DF, iirc we have seen one "labeled DF" so far after 10 yrs of looking. To be specific with my question: Would the first or only version of DF have rod in fuel line? If yes, pardon my repetition but i am curious if there is some confirmation we can reference, someone/somehow/somewhere that, that DF --> MSR makes FIRE , also seen here LATEST MSR items , -or- that the DF model, has a rod (not cable) in fuel line? thanks
