Has anyone replaced the auxiliary burner bowl and rings on a 2-burner stove (e.g., 425 series) with a set of the larger main burner components?

While using a griddle with my 425 there is always a significant temperature differential between the main (right) and auxiliary sides of the stove. Makes cooking pancakes a challenge. I wondered whether a stove with two ‘main’ burners might improve the temp uniformity. 

Anyone ever attempt this?

Thanks,
Jay

Use two 500s or 500As.

I played around with adding rings and swapping burners on a 426 last winter. Maybe you can find the post. My conclusion was that no combination worked any better than what Coleman designed.

A Preway might solve your dilemma.  At least on a Preway 'Wedge', both burners have the same output, making it a really sweet stove.  I don't know if all Preway's are like that way though.  I hadn't thought about the burners being different, but on a Preway, the path to the second burner is curved, versus Coleman where it's a 90 degree turn.

IIR the Preway also feeds in the center,  so the "load" is balanced.

Not the 4821 "Wedge" at least.  I don't know about others.

The difference in temp is a bother but you get used to dealing with it.
If I was gonna play with this I would take a ring out of the main burner and add one to the secondary burner. So far I have not had the ambition to mess with em.

Someone here--I think Hikerduane--made a two-tank, two main burner stove from a 426, IIRC. that would solve the problem.

But two 500s or 500As would do the job very well, especially if you can fab a case to hold them, like the marine stoves.

Not everyone has a pair of 500s laying around! 😁. However, a pair of 502s might do the job, enjoined in some sort of case.  Still, I can’t bring myself to retire the 425–it’s been used since the old man bought it in ‘49, I think.

Never occurred to me change the NUMBER of burner rings between main and auxiliary.  I might give that a try.

Isn't the main and secondary burner different sizes?  I don't think its only ring count.

Yes they are  different sizes.  But no reason you can't remove a ring from main burner, and put a ring (obviously from a donor) on the secondary.

Been there, done that. Search might find my post. Basic read from that  was that Coleman did the job right the first time. I have to go home now....

Some of the 413s use the same generator and gas tip as some of the 426s. I see no reason why you couldn't run two main burners on a 413 if you can supply enough air and fuel for a main and two auxiliary burners on the 426. The 413 is the large two burner, the 425 is the compact and uses a smaller generator and probably gas tip. You might just have to experiment and see what you can come up with.                  poppa

I think to make the two closer in output, you're gonna have to take a ring from the main burner.  I don't see where Timm every tried that, or maybe I missed it.

He adds a whole main burner to a two-burner at one point, it's a long post.

I read that, that isn't gonna do it, I could certainly be wrong, but methinks you are gonna have to remove a ring from main.

I think that if you want equal output from the main and secondary burners, you're gonna need to choke the main. I'm not sure if just removing a ring will do the trick, but it's worth a try. Problem with choking down the main, of course, is keeping enough heat to generate enough gas for both or all three burners. I've noticed that my 426A likes to have the main burner going pretty much flat-out when simmering on the secondaries.

Another solution would be to go with an old cast-iron manifold 3-burner like my Preway P4823, which has the main burner at one end instead of in the middle. The two secondary burners are independently controllable, so can both be set to the same output.

Gives you room for a small griddle and a pot of wash-up water or skillet of bacon on the main.

poppa may be on to something here.  Timm's prior testing was with a 425,  not a 413.   So are all 413's using the larger 426 genny?  or only particular Models?     The genny comparison list I have has no stove gennys listed...

Hmmm I have an over-sized tank with an over-long fatter genny I've never figured out what it fits...

And are 413 genny's too long for a 425? I don't think I even have a 413...

All the 413s I've worked on--maybe a half dozen--use the same gen as the 426. The gens I have include several that are stated as being for the 426 or 413, no model letters.

The 413/426 gen is too long for the 425, and the tip is too fat. If you have a 425 you don't mind permanently altering, both of these problems can be dealt with. But you still have the problem of keeping that big gen hot with reduced output from the main burner.

While 500s and 500As are a bit hard to find--I own the only two I've seen in the wild--502s are fairly common. It wouldn't take a rocket surgeon to make a case for two of them.

Yeah, I'm thinking a pair of 502s might be an interesting and fun project (whether or not it solves my 425 griddle problem! )

I have put two main burners on my 4Ms and a Canadian 414, the solution is to find a restrictor plate with a hole about 3/4", I am not sure the model of stove I took them from but they do seem to be in a lot of the 70s to 80s stoves.
I did this first on a 4M and did a boil test with two identical pots and they boiled at exactly the same time, and when I use a griddle on the stove it heats evenly according to my IR thermometer even on a simmer (secondary burner wide open).
If anyone is interested in more details I can provide more information.
Enjoy 😁

Wow, I think this is going to be a HOT topic, Got a reply within minutes of posting 😯
The configuration of the burners as follows, Main burner is untouched 4 flat rings, 3 wavy rings with a restrictor plate with a hole that measures 0.86", the Auxiliary burner is a standard main burner from a 4M,  untouched 4 flat rings, 3 wavy rings.       DSC01692.jpg 
DSC01693.jpg  Need to find a nicer 4M burner for the Aux, this stove was NEVER Lit, Still has the price tag on it!

DSC01694.jpg  I know, It needs a wash! 😊

I believe Timn means this was pretty thoroughly thrashed in a prior thread or three, but I believe you managed to bring a slight variant to the table with the restricter plate.
