Hi guys, 

It's my first post and am happy to be a member. I just got this stove and it's very nice but it definitely has its quirks. I've attached a video of the flame sputtering, even after running for about 15 minutes. I also noticed that compared to my 533 stove, this one gets really red hot. I think that's why my blue flame kinda goes away once the pieces are red hot, it seems to change the flames color. Despite this, it burns relatively OK and can boil water no problem. Also, the flame control lever seems to hard click around halfway, almost feels spring loaded, whereas the 533 is smooth with a slight click at the halfway point. I am running Crown Camp Fuel since it's much cheaper than Coleman Fuel. What do you guys think?

Side note, prior to this I used it once and put it away. Next time I took it out, the check valve was stuck which made it impossible to pump because it was too hard to push the plunger. I put some liquid wd-40 into the tank and on the inside on top of the check valve. After shakin' and pumpin' for a few minutes, wd-40 shot out of the thumb air hole and everything was clean and clear. Just a tip for anyone who may encounter that issue.

It's not an issue with the wd-40 residue because this was happening before I ever introduced wd into the system.

Welcome to the forum from Colorado.

Was this a new in box stove like the one at the link or is it a used stove?

Does the flame adjust properly by rotating the red knob or is it always running full power?

When opening the valve you are depressing a Schrader valve core, so maybe that's what might feel springy? Also, when opening the valve you are pulling a wire out of the generator. This controls the fuel flow coming out of the generator.

I don't have a 533, but I think it uses the same generator as the 442. Typically, we try to diagnose problems into 2 categories, that is, above the valve or below. If it seems reasonable to you, you might try swapping the generators between the stoves to see if the 442 acts better with the other generator. If you don't want to try swapping them, open the fuel cap to eliminate any pressure, then remove the generator nut, lift up on the generator just enough to see the tip cleaning wire hook and ensure the tip cleaner wire hook is properly attached to the eccentric block. I could see that making it feel springy, too, if it was disconnected.

Some of these stoves sputter like yours is doing. It does look like a little fuel is getting below the burner between it and the heat shield. These stoves get hot. Glowing red like in your video is normal. 

You would have to take apart the fuel valve to see if the O rings are in good shape. If they are not, that could be your problem with the vavle hanging up. Also, the wire in the generator could be hanging up. In the photo in the last post, make sure the hook on the end of the generator is in the little hole in the block that is in the middle of the fuel valve. 

Each stove is a little different and has it's own personality. Some of them will do one thing but the next of the same model will not.

Thanks for the replies. The stove was bought used but was not used much at all. The flame does adjust from low to high seemingly ok. I own quite a few coleman stoves and haven't seen the sputter between the burner and heat shield on any of them. Also, it gets MUCH more red than that. The entire heat shield gets cherry red, the 533 does not.

The springiness of the knob is strange. When pulling it slowly from full blast to halfway, you can feel a click that almost pulls the lever quicker towards off position.

Sounds like i should take apart that generator, examine the wire, and clean it out with some carb cleaner.

The clicking feeling/noise could be cause by a couple of things, but since you say it is at the half-way point it is likely the valve lever pin camming over as it gets past half-way. Also, as @MotorcycleDan stated, an O-ring might be worn and this is causing some binding in the eccentric block. It appears that you have some familiarity with Coleman stuff, so are you okay with checking out a few things, for example, removing the generator to see if it acts the same way, or removing the valve stem to inspect the O-rings? I have an extra valve assembly for this stove, so maybe I'll go check to see if it feels different when the F/A tube is removed, etc.

What was the status of the gen tube cleaning wire hook connection?

How does the stove work when you throttle back the flame? Does it get to a nice low blue flame?

I grabbed that spare valve I have and rotated the lever while applying some pressure to the eccentric block. When I do that I can feel and hear what you describe (clock at half-way and a little springy). So, I think you have some friction in the generator tip cleaning wire or the hook is not installed where it belongs. This is why I was asking if the stove's flame adjusted properly.

I am going to take it apart later today. I only have blue permatex on hand for sealing the threads back up, is that ok or should i get something else?

I'm only talking about removing the generator from the valve, not removing the valve from the fount. There is no sealer on the generator-to-valve fitting. Is that the part you're thinking about?

Does the stove's flame adjust high and low?

OK one less thing to worry about then. Yes, it does adjust from high to low...although it is pretty sensitive while trying to adjust to the desired height.
