Cleaning a Coleman 425 Dual Burner Stove

Here is a video on how exactly to clean a Coleman 425 Camping Stove

There are many, I'm sure, useful videos about cleaning and maintaining a Coleman stove, but yours came right to the point of my problem and showed me concisely exactly what needed to be done. Thank you.

For the inside of the stem - Remove the spring and use a 22 caliber copper cleaning brush . Carb cleaner = Yes . This will also clean a check valve on a lantern or stove .
This is a great video and Thanks .

People. Don't worry so much about what the parts may or may not be called. *It doesn't matter* unless you are looking for replacement parts. This is THE MOST important maintenance to know how to do with any model, liquid fuel Coleman stove. My only advice is to *not remove the end fitting too often* - clean the tube with it on if you can. The fitting is brass and eventually, after removing it a number of times, the softer threads will no longer be able to make a good seal. Ask any plumber about brass threaded fittings. There is no gasket material or plumber's tape that can withstand the heat this part achieves when in use. This causes a small amount of gas to blow back out of the "carburetor" (the large 'U' shaped tube in the back) directly into the flame. It's not dangerous but it will burn with a sooty, yellow flame and partially disrupts the flow through the carburetor. (yellow flame = carbon-monoxide and blackened pots) The other tip is; once you've cleaned the brass rod with '00' (or finer) steel wool, use a metal polish on it. That seems like over-kill, but the smoother the surface of this rod the less it clogs up while in use.

Followed your advice and my stove now doesn't sputter. Thanks.

Thanks for the concise video. I used GUN CLEANER to clean everything. Worked really well !

I am just watching this and thought I would suggest for those with gun cleaning kits that they might fit the stem tube. May be 22lr?

Thanks for posting this video, I recently found a stove which needed a good generator cleaning and now it works great.

Coleman stoves and lanterns, or I should specifically say...stoves and lanterns that run on Coleman fuel are VERY underrated in my opinion. They often seem overlooked in favor of their kerosene burning brothers.
Coleman fuel is low octane, unleaded gasoline. Incredible amount of BTUs! Immense heat! Alcohol stoves can’t even compete in the BTU arena with these.
Kerosene may have more BTUs, but kerosene is combustible (less volatile) so the stove generator of a kerosene stove requires several minutes of preheating. So you need 2 fuels and some spare time to get a kerosene stove in operation.
Coleman fuel, aka white gas/camp fuel/gasoline is highly flammable so the generator doesn’t need prolonged preheating and it doesn’t require any other fuels to get started. Gimme a Coleman fuel stove over those other 2 options any day! It can take you 20 to 30 minutes to boil 2 cups of water over alcohol. I boiled 8 cups of refrigerated water in 6 minutes on a Coleman stove. 64 ounces from 37 degrees to 212 degrees in 6 minutes. That’s BTU city! For kerosene, add another 4 minutes to preheat the burner and another minute to get the pressure and flame up to the task. Not saying kerosene doesn’t burn hot, just that it takes longer to get it started. Also, in head-to-head testing with a CO meter, Coleman fuel emits less carbon monoxide than kerosene. It burns cleaner.

Excellent video. I use my older camp stove everday (not dual fuel type) and I use regular gasoline in it. It carbons up faster but the price of 87 oct make more sense as this is my only cooking device. I have learned how to clean the needle and stem and is regular maintenance but have not been able to get the carbon buildup spring out for a thorough cleaning. Any suggestions would be appreciated, and thank you for a well done tutorial.

hello my friend, thanks for your tips. Now I also have a question, I have a Coleman 523 cooker, unfortunately there is black rust or gummed-up impurities in the tank. what is the best way to clean the tank? thanks in advance.

[noexcuses]

the "stem" as you are calling it is actually called the Generator which, once hot, vaporizes the fuel.

Thanks a million!I turned it multiple times but it did not stop just spun.I followed your instructions and it pressurized easily.When I inserted it and tried to light no go couldn't hear gas sound.Fuel was left in the tank when from return.Suggestion please.Also whoever returned only lit one burner.Thanks in advance, Aaron

I own a Coleman 428-700 3 burner for 20 years I need to clean the generator tube. This will help. Thanks.

Thanks for the clear and concise video. It was very informative.

[twnstr]

Awesome video!!! Very helpful! Thank you so much for the clarity and great examples. I really appreciate this.

Excellent video very well explained and thought out.
Kudos.

Thanks, this is my issue too i think (same as u couldn’t find the right info online). It would be nice if u demo’d the problem so we could see that. U know, for trying to determine if we have the same problem u did. Great vid tho! Appreciate u making it!

I have purchased a new in the box return from goodwill Coleman dual fuel I believe 424.When I try to pump it it seems like it is already pressurized.The pump will not push all the way in to lock .I tried twisting it counter clockwise and this helped however I can't release thumb pressure to twist it a couple of times to lock.Any suggestions never used these models before always a propane stove.Most appreciatively aaron

Vinegar cleans brass really well. You don't want too much abrasion on the stem end

What if I don’t have pinkies? How tight then?
