Coleman 2-Burner Unleaded Camping Stove 2020 camping cooker

Product Information

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.

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. I bought my barely used 424 Duel Fuel after my 425F quit working. I had the 425F since 1980. It never failed me. 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 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. It was brand new, so I didn’t think the manifold was clogged. I pressurized the tank, detached it from the stove, and just tried to spray fuel into the air. This didn’t work well. The fuel seemed to be spraying out behind the tip and not through it. Some fuel dribbled out, some sprayed out intermittently in different directions, and a good deal seemed to build up in the generator itself.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. I've cleaned out the burners themselves, but perhaps I'll take another pass at the expansion chamber area. But I am trying to figure out how the initial fuel-into-the-manifold should be working, to see if something is too rich or igniting early. 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..

You draw a line about two inches from the bottom of the bottle, fill the bottle with water to this line, then add the fuel you want to test, cap the bottle give it a good shake, let it stand for a few minutes if the water increases you know it’s got ethanol, and if it is less then 5% ethanol the line might drop slightly but if it holds your good to go, and if you can lay your hands on a graduated cylinder you can actually calculate the ethanol content, but if your in the middle of no where land (yes I’m envious) a bottle and a felt pen or even a piece of tape for a line shouldn’t be to hard to find.. Normally I will use a long skinny bottle so you don’t waste to much fuel, and I save it for later and use it to start a fire. 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 The Coleman Collectors Forum was originally the Old Town Coleman Bulletin Board Service in the early part of this century. In December of 2008, it became the forum as you see it today. It is a forum rich in knowledge of Coleman and other Gas Pressured Appliances. This "richness of knowledge" comes from those that come here and share what they know. 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…. It’s mobile: we not only can choose to cook inside our outside of the Land Cruiser, but we even took the stove on a glacier trek in Pakistan.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. 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.
