After a week when it snowed and rained a lot and the roads were blocked, I got this Optimus 111_B oven. Because the seller had already sent a video about the health of the stove, I safely poured kerosene and turned it on, it was great, but the flame did not have a uniform sound, the sound was choppy, maybe it is because I did not use gasoline, maybe it needs service. In any case, I quickly turned it on out of curiosity and taste But its heavy weight compared to the Russian stove worried me because it weighs twice as much as the Russian stove and it seems to be heavy for climbing.
Hi kind friend I also like the roar of this stove. This is an instinct that is not found in all humans My father, who passed away many years ago, enjoyed nature and hunting a lot, and I inherited this gene from him. I wish you a happy time
Yes, these are heavier than the Russian stove you showed us but it should be able to cook anything you put on it without problem. It looks like you have the original seal in the fuel cap so a new seal will help with better performance. Also, the 111B (B is for bensin) runs best on white gas or pure gas. Kerosene will not give the best results. I think this 111B is the best stove you've shown so far. Good luck.
@The Warrior Thanks for the excellent and beautiful video from 111 B @Ray123 Thanks for your tip about the letter B (bensine). A very interesting point, I will definitely test it with bensine There are no spare parts here, I will try to restore the same parts, thanks for the help
Even though the fuel cap seal looks original it may still be good and not leaking. You can test it by pumping the stove and then applying some soapy water around the cap. If it's leaking the result will be bubbles that are easily visible. If you need a new seal we usually use viton rubber but I think nitrile rubber can be used too. The main thing is they must be fuel resistant. You can make a seal yourself if parts are not available in your area. I enjoy your posts about your stove finds and testing and your trips to the mountain. Please continue!
The reason for the oven's weight is due to its strong and iron Samsont housing, with a half-filled gas tank, it will weigh 1700 grams. When the stove is off and there is gas in the tank, due to the fluids in the gas, pressure is created in the tank, and like an old man with a prostate, it leaks a little from the jet, and this pressure causes the pump handle to be directed outwards. And leaking the smallest drop of gasoline in the backpack will cause an unpleasant smell unless we carry the gasoline separately and empty it into the tank when using it, which is a difficult and time-consuming task. Considering that this oven was previously located in the north of the country and next to the Caspian Sea, the tank and iron shield are rusted and I don't know how to fix it.
@kohdarmiansali As others have said, this is a stove that very nearly does what you want. But it also is dangerous. The pump handle rising shows the non return valve is failing. The gasoline in the pump can ignite/explode. Yes they are heavy, but even mountain climbers carried this family of stoves because they work very well, have few issues and survive injuries. But this one is sick and dangerous. The NRV (non return valve) can be fixed. It MUST be fixed.
@JP2 Hi dear friend Thank you for your guidance If possible, please send a more detailed explanation with photos and links, I am not familiar with the terminology of nrv Thanks for your efforts
Hi dear friend Thank you for your guidance and encouragement in repairing the oven and climbing sports, hoping for a day when God will give you a long life and good health To be able to travel all the mountains and beautiful nature of the world even in sleep
https://classiccampstoves.com/threads/optimus-111c.41019/ The NRV is part 2250 "pump valve" in this instruction for a later Optimus 111. The pump and fuel tank design is the same as the 111b. Instructions for replacing are on page 4.
Hello Dear friends Tonight, as you instructed, I poured gasoline into the Optimus 111B nozzle. We had tea with friends in the cold and frozen weather and we were all happy with the excellent, roaring stove and beautiful flame Thanks for everyone's attention
Good Evening, @kohdarmiansali, As an aside, I was a wrestler in High School, and also in College. On our College team, we had some excellent wrestlers from other Countries, including two from Iran! Is wrestling still popular in Iran today? I hope so! Sorry to get off track, but I had to share about my two Iranian wrestler friends! As for the 111B, I had several of them, and a 22B, long before I ever saw my first kerosene burning 111. They always served me very well, including one trip where we climbed up the back face of Half Dome, in Yosemite National Park. Heavier than other stoves? Yes. But, they are also more powerful and much more stable than other stoves, too! Because of the highly flammable nature of gasoline (Coleman Fuel in the US), 111B owners need to make sure to service their stoves when the gaskets and NRV and SRV pips feel like they are not soft enough. You can get such gaskets from The Fettle Box, right here at CCS, if you should need them. Congratulations on scoring your 111B. It's a fine stove, and a wonderful performer! Take care, and God Bless! Every Good Wish, Doc
Hello my good friend Thank you for your attention. Yes, Iran has had good positions in the world in the sport of wrestling since the past. Send my greetings to your Iranian friends I am also satisfied with the good performance of 111b. I took it to the mountain yesterday and its roar broke the silence of the mountain. I am grateful for the privileges you have given me, which I may not deserve Be in the protection of the great God
