Coleman 2-Burner Unleaded Camping Stove 2020 camping cooker

Product Information

The firepower and the flame control were superb, and the flame extinguished immediately when the control knob was turned off. There was no lingering flame in the burner. (Caution: if you max out the flame while using only the main burner with a wide frying pan covering the most of the grill, the paintjob near the fuel tank will burn and darken. The main flame gets that large!)

These stoves have gone everywhere from tailgate parties, multiple week hunting camps, emergency cooking in a week long snowstorm at my home, not to mention the inumerable family outings. My dual fuel stove has performed outstandingly all these years. I had one hiccough at a concert where the stove would pop then go out but I just unscrewed the needle valve, cleand it then continued on cooking. This stove takes a little skill to use but once you get the hang of it, it will be a camping buddy for life. On 425F, the secondary burner is so small, it takes too long to get a liter of water to a boil. It is only good for simmering, in my opinion. Now 424's secondary burner will bring it to a rolling boil. Now you can cook the pasta while you get the meat sauce ready. I have a older Coleman 424 2-burner camp stove, and am using Coleman fuel. I am having some trouble getting it started in normal warmer weather, and have occasion had the huge-flaming-metal-box to deal with due to excess fuel burning off.I recently bought a Coleman and it kept burning at the tip and also lighting the manifold on fire when I tried to run it. When I turned the valve off the tip would burn for several minutes as the generator was full of liquid fuel. If you have to burn methanol, like say in a marine environment get a stove made to burn it like a Trangia 27 they are very reliable, simple and safe. Reply If your going to burn diesel long term get a stove built to burn it, like a MSR wisperlite international or there dragonfly international ( they burn pretty much anything and simmer nicely ) but take a rebuild kit or two because you won’t find parts outside of north america / Europe and don’t expect a 50 year life out of them like coleman stoves deliver they have to much plastic in them to last that long, and they are not built for cooking for a crowd four to six people are about the max … Reply Just after I opened the box, enclosed owner's manual for 424 showed me how to fix the generator problem. Instead of buying a new one, I just cleaned the needle (with 220 grit sandpaper) and the coil (with a Dremel wire brush) inside the generator tube, and reinstalled the assembly. I wanted to install a new one, but the local hardware store priced it so high, that it was not worth buying for a 23 year-old stove. My 425F now works just as good as the first day I bought it.

Be mindful the generator might still have fuel inside it which will burn so do it outside, keeping your fingers away from the ends and don’t look down the tube while it’s hot in case something hot and burning happens to spit out of it.

65212 Coleman Unleaded Stove 424 Pump Cup and Clip

But it is easier once you know it’s ethanol free to fill a Jerry can at the pump then making your own. Testing fuel for ethanol is actually very simple, all you need is an old water bottle or glass bottle, a felt pen, some water and fuel you want to test. You might also want to make a metal screen globe and lose the glass which will at some point end up getting busted no matter how careful you are, just cut some metal window screen the same size fold the edges over so there is nothing pokey, and stitch it together with wire so it’s the same size, they work like a champ and don’t break and protect your mantle from stray bugs.. My 425F always had some of the lingering flame, and it had increased somewhat over the years of use. I used to pull the generator out of the expansion chamber, so I do not have to smell that nasty, incomplete combustion.

If you use a larger bottle, pour off the gas, and toss the water add some epson salts (Magnesium sulfate, common bath salts) to the bottle of gas shake it, let it settle, let it clump in the bottom and filter it again, and you will have ethanol free fuel..

Our Verdict

I recently acquired a Coleman 425 stove from the Goodwill so I thought that I would sit it next to a 414 and take some pictures to compare the size of the two units. The 414 is the larger with the silver fuel tank and the 425 is the smaller with the red tank.

Right now, after lighting/warming up for a minute or two and turning the lighting lever down on the right side burner, the burner flame is bigger and yellow, and I am getting some flame out of the tube learning into expansion chamber in the manifold, and flame in the expansion chamber as well. Often, I get sudden popping and a "jet-engine" sounding noise from that area. Oddly, if I engage the second burner, it seems to get both burners working normally steady-state with nice clean blue flame circles. I think the quality of the housing has worsened over the years. I would love to buy a stainless steel version, even if it would cost a fair bit more…. The lanterns get used lots because make great heaters,just drop one behind your chair while sitting around the fire at night, you’ll burn them for hours once you try it… (yep I laughed at first and called someone a wimp when I seen it, but once I tried it, I went out and got three more lanterns the next day)

But the simplest way to fix a dry pump cup is to just pull the pump out let the cup soak in oil for 10 to 30 min wipe it off so it’s not dripping, reinstall and then add a drop or two every week, brake fluid works great for this since some brake systems use leather parts and it make them last longer ( just don’t use it in your brake system if the bottle has been open for more then a few days as it’s hydroscopic and will absorb water overtime affecting your braking system or if you have dropped the pump cup in the bottle, any sediment in the bottle won’t do your brake system any favors, I normally just use the left over fluid saved after doing a brake / clutch job since, if you’ve done the job right you won’t ever need any more fluid) Reply
