Anyone got any advice for me on a Coleman Model 533 Multi-Fuel stove?
Amazon.com: Coleman 1-Burner Dual Fuel Sporter II Liquid Fuel Stove: Sports & Outdoors

I bought this apparent piece of junk about a month ago and have
experimented with it twice, getting the same results:

Fuel it up, pump it up, and light it according to the operating instructions.
It runs fine for a few minutes, and then the flame starts to die down.
I've got the control valve open about halfway between off and full-on.
That seems to produce a decent flame at first, but like I said, give it
a minute or two and it starts to die and eventually snuffs out.

I tried turning it up a tad higher to keep it running. If I do that, I get
very tall (6" - 8") and yellow flames, which I believe is an indicator of
poor combustion (too much fuel vs O2). Nice blue flames is what I think
I'm after.

It will stay lit with the flames leaping high like that, but it doesn't take
too long for the flames to creep down under the burner pan. At first
its just a small flame, but give it a few minutes and the entire top of
the fuel tank is covered with fire.

Takes a nervous few minutes to shut it down at that point. I turn the
valve to off, but it continues to feed fuel for a minute or so. Its almost
impossible to snuff out while there's still fuel available. Short of emptying
a fire extinguisher on the thing, its just got to burn out on its own.

To my thinking, a pressurized metal container, filled with fuel, on fire,
doesn't so much resemble a camp stove as it does a bomb. (Maybe
I'll just let it run and post explosive results in a video on YouTube. :D:)

I'm using coleman fuel, not unleaded gas (the other multi-fuel option)
if that makes any difference. I would have figured it would run better
off the supposedly cleaner coleman fuel.

Anyone got any input? Have I got a lemon that needs to be returned?
Are the Coleman 533 stoves just junk? Or am I having a case of the
stupids in how I'm running it?

Thanks for any input.

Is it a new stove? I have one and have had it for years. works great for me. I light mine as follows: Make sure it has fuel. Pump it up. Turn on valve just until I hear fuel coming and light it. Then I pump it up some more, until it feels solid. If it seems to falter, I will then turn the valve open a bit more until the flames get big and then turn it back down. I don't leave it burning wide open until the flame turns blue. To run properly, the generator needs to be heated up. That's the tube that runs from one side of the burner to the other. Once it heats up, then the flame should turn blue and heat the way it should. If this is a used stove you may need a new generator. If you are new to Coleman stuff, it takes a bit of experience to be able to use them safely. Once you get the hang of it you won't want to be without one. I have a single burner Coleman in every vehicle I own, as well as several two burner stoves, a three burner, and many lanterns. They can really save the day when needed. Good luck.

Are you pumping it about 100 times? Also you may have a leaky cap especially if it was stored with the cap tight. Always back off the caps and leave them no more that finger tight when you store them, also did you oil the pump, sometimes the check valve sticks and gets leaky if you don't use oil. Usually if you get the stove to light the generator is ok. Generally if I buy used coleman stuff I buy a new cap and pump on general principle.

Yeah, it's a new stove. Only tried it twice, the same flammable results.
So the generator should be fine, assuming its not defective right out of
the box.

From both the response posts, it sounds like I'm not pressurizing it enough.
I thought I read to pump it 30 times. You guys say pump it up 100 times,
or light it and pump it up some more. Sound like I need to go back and
re-read my instructions again.

I'll give that a shot before sending it back. Thanks.

(Still doesn't make sense to me why the entire top of the fuel canister
would burst into flame -- unless the under-pressurized fuel isn't properly
vaporising to the burner, and is instead staying liquid and dripping out
below the burner.)

I'll give it a try. Watch the news or the horizon for a fireball. :D:

Good tips on how to store it, and oiling the pump. Will do.

Once it warms up it should be fine. I have 5 or 6 of these stoves and I love them. It does take a bit use to get to know them. When you fill it up you need to leave a bit of air space at the top of the tank. If you over fill it there is no room to pressureize the tank and it will flood it, which generally gives the result that you are getting. I like to only fill it to the point where I can just see the gas in the tank, just a bit above 3/4 full. Hope that helps. Tom.

I've got a 533 as well as three of its older cousins, going back to at least 1981, if not several years before that. To date I have never had a problem with one. I've used them successfully in the cold and at high elevation (14,000-15,000 feet). I've replaced generators, but other than that, they always work. And each one is well-used. It sounds like you've been given good advice, so all I know to say is don't give up on it yet. Good luck.
