Coleman 425E secondary burner not enough gas

My experience with one of these plus a primus 77 and kampkook with a similar burner setup is that the secondary burner only really works properly when the main is at full power. Turn the main down a 10th and the secondary goes down a quarter. Can make for quite a bit of juggling to simmer 2 pots. As to why my guess is the velocity of the fuel air mix slows down at lower main burner settings so less goes to the secondary.

 

thanks -- i'll have to play with the settings.... I guess it is a juggling act. I've never had a two burner stove.. I think the stove is pretty functional now, and appreciate all the help! you guys really pulled me (and my lil stove) through!

 

You'll need to do this. )

You need a "bottle brush" with a bendable wire handle long enough to push all the way through the tube. If you use a wire brush, it needs to be a bit smaller than or equal to the inside diameter (ID) of the tube. A nylon brush can be a bit bigger than the ID. I've found wire brushes like that at hardware and auto parts stores, and I found a nylon brush made by Weber BBQ company that has a flexible handle. Either kind will work. It's handy to have these brushes, as bug nests are almost always present in garage sale Coleman stuff (and sometimes even in mine).

Are those at the local sporting goods stores?

 

You'll have to ask for one.

LOL!!

 

thanks, arch......... well, I ran a stiff wire through the manifold, and shook it the stove in case anything came loose... I think that'll do it for me.... stove seems to work ok. the secondary burner seems good. i think one main thing was moving the restricter to the main.

thanks again all. you guys really stuck with me. if I have more questions i'll post again!

 

Good for you.
Now, when you find a 413.....

 

A trombone slide cleaning brush (nylon bristles on a coiled wire) would be ideal for this. If it is too large in diameter (roughly .60 inch) then perhaps a trumpet "snake" would do the trick, smaller diameter. A tuba "snake" will be too large I'm sure. Available at any music instrument store.

Give it a try.

what is nicer about a 413 --- I know the 'surface area' is larger, but is that it? and -- if the burners are the same as a 425, I am not sure I can see the secondary burner being powerful enough to use a big pan or stew pot....??? but all I have to compare things to is my current 425......... i'm growing fond of it, since it is working better......

wow - good ideas......... but might they toss me out of a music store if I tell them I need the brush to clean my camping stove?? but I looked online, and those brushes are like $7. I thought they'd be like $25 or something. i'm not musically inclined, tho.

 

The larger size of the 413 is very useful in camp. The secondary burner cooks a big, full stew pot just fine.

 

You might be surprised. Most of the time you will be using only the main burner, once the stew is hot, the seconday burner will keep it plenty warm if you need the main for something else.
As to 425 vs 413, it really just depends on how you plan to use it. If you are car camping but cooking with mostly backpacking-size pots, you'll not need a 413. But, the 425 gets crowded with two decent-size pots or fry pans -- can't really center them over the flames. I have a 413 out on my porch that I use on a regular basis this time of year, a 425 would work but not without some irritation.

 

Especially once you try a 413.

 

i'll have to try the 425......... then see where I go from there... looking forward to it

 

Nothing wrong with a 425.

 

gtk!

 

@snwcmpr, don't incite him.

I thought I was doing the opposite.
I stopped mentioning how much better I like the 413. I mean I didn't say, again, how much bigger the burners are.
I didn't, I didn't.

Besides Duane, Ken didn't say anything at all about a 426. No he didn't, even though everybody knows real men cook on 426s. But Ken didn't say anything at all about those because that would have just been stirring the pot so to speak. Good on you Ken for practicing restraint and not saying how wonderful the great 426 is.
