Make sure that there are no obstructions in the fuel air tubes, the slightest bit of blockage can cause the flame to burn rich/yellow no matter the fuel. The rotary valve with the knob is two stage. When you open it a quarter turn, it only allows fuel vapor in from the top of the fuel pickup tube that's in the fount (fuel tank). When you open it up more, then it starts to pick up liquid fuel. This is why you only open the fuel valve beyond a quarter turn after your generator is up to temperature, and when you do open it, open it all the way. Thank you for posting this, it was great!
The jet size in the generator is two large for kerosene/diesel. You would need to drop the jet diameter by 0.001"- 0.002" of an inch to get the proper fuel to air ratio for kerosene or diesel. Your atomizing/vaporizing the fuel it's just to "rich". Kerosene and diesel contain many more btu's than Coleman fuel or white gas and need to be run at a leaner ratio.
Back in the 1930’s the John Deere tractors ran on distillate which was half diesel and gasoline. Maybe a half baked solution but would get a few more btu’s out of the stove.
To get it to work you need to have the fuel turned all the way down on very low because the fuel is cooling the generator with it turned up high and its not heating up anough like that and hold the torch on the generator longer before opening the fuel
Good test. I was wondering the same with different fuels. But it has taught me that white gas is the easiest. Denatured alcohol is unstable, kerosene needs just a little preheat (torch not needed just tissue) amd burns very nicely. But again, white gas is hassle free and quick.
Copper conducts heat really well. Wonder if some moderately heavy copper wire (14ga seems about right) wrapped a few turns around the generator with the ends poking out a half-inch or so would help. Do that several times over the burner area so you have a wire wound generator with fins of ends poking out each side.
Yep there's some other videos of exactly this. Take neutral wire out of some old romex and wrap 10-15 times to help hold heat in the generator. Letting the ends stick out over the burner will grab even more heat. I think the generator tip will be the biggest issue though as it's a bit too large for the higher BTU fuel. It will always tend to run rich even if it is properly vaporized.
@@massa-blasta Or you could get a propane conversation generator. I know of whole houses that run off propane. I do prefer running gasoline or white gas but propane would be a proven option for inside a house.
Try it again after you check all of the air tube, especially the elbow, for obstructions like mud dauber nests or spiderwebs. They can be tricky to get out sometimes. I suspect the diesel will run fine in it afterwards with a good preheat again. I’ve seen enough of these run perfectly on kerosene and would think diesel would at least burn decent.
I watched someone wrap a Roamex unjacketed ground wire around the generator for kerosene and preheat it with hand sanitizer. Took 3 minutes to burn clean.
Coleman made kerosene, as well as white gas lanterns. There are YT videos showing how to convert from gas to kerosene lanterns, and how to run them on diesel. If I remember correctly not only do you need to preheat the generator, but you also need to change the jet. I wonder if that might help in this situation. By the way, if anyone is interested, you can find an adapter to convert these stoves from white gas to propane. I have one and it works well.
Thanks for the comment. I was actually going to get the propane adapter but they were out of stock last time I checked. I also have a 2 burner propane unit, so I don't really need it, but I thought it would be cool to have. I've seen some folks run these on kerosene with better results, so I'm sure it can be done. I'll have to keep looking while I'm waiting for the weather to warm up. Meanwhile I'm loving the MBU V3, but kind of big/heavy/bulky to camp with.
If you're having to use a propane torch to preheat the stove then in essence you are still having to bring two fuel sources. Running regular gasoline in these stoves works pretty much the same as Coleman fuel but does require occasional cleaning of the generator.
Excellent video. Im seeing a surge of these homemade stoves using diesel in parts of Venezuela. The preheat operation is minimized in some of their designs.
Thanks for your toil! I just brought home a g. 424 coleman today. I've n ever used one ever. I need a back up incase power goes out. At trailer park. You've saved me.some grief, although I don't think I would have considered diesel . I've heard stories about old naphtha stoves exploding and am very nervous about my first lighting of my stove. I did see someone use kerosene, but he had to prime with alcohol in the main burner collar cup. I'm really worried, tomorrow I need to make.a choice what fuel for the 424 coleman. I'm anxious to start cooking burgers and omlettes but too timid to light the damn thing. Any constructive help appreciated. Nervous as cat pee!
To start, you would have had to put the small tap near the tank upwards, and once it got hot enough, turn it back down, because in the down position, it will run from the vapour pressure. In an other Video I did see someone use Kerosene in such a stove, and that was a hard start too. That guy used some kerosene-drawned Aluminum foil coil to heat it up at the beginning, and it took, even with that kind of starting aid some two minutes to get it started, but then it burned pretty well. Probably you didn't start it as by the book, or the Generator was clogged, or it did in the end not have enough pressure left in the Tank.
Thanks for doing this, I have been wondering about doing this with mine (same/similar model) for 4wd camp camp cooking as I have a deisel hilux it would make good sense. These stoves work great on unleaded fuels, but I imagine to get deisel to burn correctly some of the suggestions here may help, by using a smaller jet orifice firstly, as deisel has a greater BTU/ltr ratio than white fuels/petrol or gas, maybe increase the generator efficiency by winding a decent layer of extra copper around it might help. Also, if you can increase the air delivering through the mixing Venturi this may help as well. As other have mentioned you could try mixing with other more combustible fuels until you find a ratio that works. Nice experiment, but you should have checked that the stove actually worked correctly on normal fuels first, my guess is that it will work fine on normal unleaded fuels judging by the flame you got with the deisel and a smaller jet size would be a key issue here. TFS. Cheers
He likes the idea of having one source of fuel but realizes that if there's a chance of getting diesel to burn then he'll need propane to light it, and the comedy continues to write itself.
Wot kind of man uses a funnel? Nice to know what my new to me 42 year old Coleman stove can use for fuel as Coleman fuel is 22.000 a liter and gas is 1.76 / liter where I live .One video I watched the guy wrapped the tube in copper wire to enhance the heat to vaporize the fuel?
How about a Gasoline/Diesel mix? I picked up a few gallons of this from someone who made a fuel-up mistake with their car but was smart enough not to start it. We just syphoned it out, filled with fresh gas, and a bit of cranking/smoking later, it was good to go. (Gas in a diesel is MUCH worse, from what I hear: No idea how to handle that). Wonder if it's good for this.
If you want to use diesel, simply buy a Primus stove. I have been using mine for 40 years. They are Parrifin (kerosine) stoves, but runs equally well on diesel. And, as a bonus, they look way better than the Coleman - nice copper fueltank to polish up😁
@@LeighBlackall-plus Yes. Bit of methelated spirits in the cup, let it burn for a few minutes to heat the vaporiser, and off she goes. I use Alcohol gel nowdays, its less prone to spillage an fire in the back of my 4x4.
@@kafferhond435 good tip on the gel. I'll try that too. I spoke to a mate, He mixes the diesel 60/40 and said it's perfect. But I'm going to try 100% diesel. This is great if I don't have to carry another fuel.
Put some heptane in the tank with diesel, a deciliter or so. Then it should run fine. We tried our optimus 111 hiker and that did the trick when using diesel.
Here in Canada a US gallon of white gas or Coleman fuel is 25 US..30 cdn dollars. Unleaded fuel..is 6 or 7 $. U pick. Cheaper the better..fewer additives to gum ip the works.
Wonder, if anyone has tried 🤔 alcohol ? It's clean burning 🔥 So clean sometimes you can't even see the flame...So , becareful it may already be burning and it is hard to see the flame ?
It is easy to clean, so I don’t care clog. Kerosene and mineral spirit works good. Use torch to prime and beautiful blue flame. I am not turn 100% open , 70% pure blue flame , 100% open is blue bottom yellow top flame
Long before the days of dual fuel Call man stove my father used gasoline but he used premium gasoline If you use low grade it does not work very well I made the mistake of using regular leaded gasoline in the lantern and it bursted into flames make sure you use premium no lead Gasoline
What if you tried starting up on an almost empty tank of white gas or unleaded, to heat up everything including the burner head? Then shut down, fill with diesel, and try again.
diesel works well in a 8 wick stove, smokes abit for a while, but when it gets up to temp, its great, no smoke, and cheap, well, not a momment, £1.50 a Lt,
If the stove was untested? It's not a good practice to run a non recommended fuel straight off the bat! Test new/second hand stove with recommended fuel first! If it is working as it should? You may have to service the Generator..whatever! Is it working correctly? Yes ✔/No If ...yes then change the fuel!!
