I just repainted a 426D that was beat up but working. Upon test firing, I get a yellow flame that blows back from the generator tip over the burner. It is hit or miss when it happens. Is it normal or am I doing something wrong? I did unscrew the tip and brushed it lightly with a brass brush. Thanks!

Sometimes they just need snugging up.

Let the pressure out of the tank, loosen the gen tip 1-2 full turns, then tighten it again. Test. If it still has some candling at the tip some copper anti-seize on the threads, not much, will take care of it. 

Sometimes when running it on a low flame you will get it because of raw fuel but should go away when increasing flame height. Also, check to make sure the gen is recessed into the manifold far enough.

Have you checked the burner/mixing plenum for critter nest. Are you able to see the tip of the generator with it inserted in the generator hole?.

I'll double check the plenum, I'll also put on some anti-sieze , thanks!

I put copper anti-seize and also discovered the tank was not hanging correctly. I got the fitting and hangers bent back where they should be. It still candles occasionally. Is it anything to worry about it just live with it? Using this for a upcoming trip so I prefer not to have a surprise.

Check your generator tip for a hairline crack also make sure you don't have bugs and bug nests inside the pipes.

I've never heard of any member's having 'safety' issues with a stove gen candling. 

That could change with further comments.

Make sure the stove handle is not keeping the tank tabs from indexing fully into their slots. This could keep the generator tip from fully going into the bunsen. Or loosen the nuts and screw underneath and move the bunsen/burner assembly towards the tank.

Thank you to all servicemen and servicewomen, past and present.

If it bothers you then it might be advantageous to buy a new generator. OCP just might have on in stock. Cheap insurance for peace of mind. Jeff

A picture of the flame in question might be informative.

Recently had a similar "Candling" generator tip on two stoves. The copper sealant was sufficient to stop the candling, leaking tip on one of the generators. The second generator had to be replaced. The second generator that needed to be replaced for candling as you described, slowly got worse over time. Tightening or adding the copper sealant did not help. I saved the parts.

It looked to me as though the threads on the generator just wore over time to the point they would no longer seal. They are shallow fine threads and easily damaged. A tap and die set with the correct thread pitch might help buy yet again Coleman may have used a proprietary thread pitch. If nothing fixes the candling, if available put a different gas tip on the generator. This may shed light on if it's the gas tip or the generator threads, if you don't see any cracks.

If this is a stove you like to use. Just cut to the chase and buy a new generator. But that does not mean throw out the old one. I like to see if I can determine what caused the problem and then save what parts I can for spares.

I use Rutland wood stove gasket cement for this common problem. Take the gen tip nut and insert out. Put a very small amount of the cement on the tip insert where it goes into the gen tube, and another very small amount where the nut bears on it. Let it dry for an hour or two, then fire it up.

I have never heard of this leak being dangerous--just irritating, as it will leave soot on the bottom of a pan.

I have no idea how to translate any of that to French!

Thanks everyone for the help. I did a long burn on it to test how long it takes to boil a large coffee pot of water. There was no candling this time around. I have tweaked things and hopefully got the tip into the burner tube far enough.  Issue this time was black crusty soot on the grate, but not the burner. This stove sat for who knows long, I am hoping a dose of really fresh fuel will clean it out and solve that problem.

If you're getting soot on the grate, look for a clogged tube in the burner manifold and Bunsen (the thing the gen tip sticks into). Soot is a sign of a rich fuel/air mixture, and is almost always due to some small arthropod taking up residence in your burner assembly. It only takes a tiny amount of spider web to cause the stove to run rich, but wasps find those cozy spaces irresistible for building their nests.

Just wanted to provide an update, we ran the stove A LOT for 6 days on our trip. Worked great and worry free.  Some off and on candling and a little soot, I'll tinker some more.  Just wanted to say thank you again.

I've got a Sears stove I use a lot, it candles about 30% of the time I use it, tip is tight enough, have not removed it yet...someday.

Center burner can run too rich if you aren't using the secondaries, I wouldn't worry much about a little soot.

My 424 did that, it was spiderwebs. Easy to clean, no more candling.
Love my old school Coleman liquid fuel gear. Looking for tips and tricks to make the most of it.
