Got my solution by talking to a fellow at REI. He showed me how to take the Coleman apart and check for problems.

Coleman 424 duel fuel stove leaking fuel at control knob. Took that whole section apart today and it seems there is some sort of dark grey hard putty like gasket material in the joint there and I guess it...


A complete new valve assembly isn't very expensive and you can often get one on eBay with a new generator included. It's not worth servicing the old valve given the safety implications of leaking fuel.

Colman stove won't light


Here's the way these oldies work:
1. Make sure you've got fresh Coleman fuel or equivalent in the tank.
2. Make sure the cap is tight on the tank.
3. Unscrew the pump knob counterclockwise about 1/2 to 3/4 of a turn.
4. With your thumb covering the hole on the pump, pump the tank about 15-20 times, then screw the pump handle tight clockwise.
Then you can turn the little lever knob to the light position (I believe it is in the up position) and then crack the fuel knob open a bit and attempt a light of the burner with a lit match. As it warms up you can turn the lever to the opposite position to obtain a good flame...
Best to try this before you leave for your trip...

My coleman 424 stove has been sitting in shed for a coulpe of years, now got it out again. Filled with petrol when pumped up I can light it but flame only lasts a few minutes then it dies as if no...


My best answer is that your pump seals have dried out and are allowing pumped up pressure to leak back past the pump seal
Try this: DO NOT LIGHT THE STOVE
Pump it up hard then quickly attach a small balloon with a rubber band around the base of the pump - where it contacts the tank. A deflated balloon or a small plastic baggie - does the balloon begin to fill with air after a few minutes - if yes then your seal is leaking.
You might try taking the pump apart and soaking the seal overnight in fuel reinstall and see if it cores your problem
Good Luck

Here is Coleman's repar part website.
You may want to replace the valve if it is leaking.

Coleman 424 Dual Fuel -- High, yellow flame


Are you pumping the tank up all the way? I have the same problem if I have too little pressure in the tank. The instructions say pump 35 times. Try pumping 50 or 60 times- that seems to help.

Also, you can't light this one like an old 425. My old stove you could turn the gas on and then take a match neat the burner. For this stove, hold the match near the burner with the gas off and quickly turn it on.

These are two things that seemed to help me with the same problem.

Having a problem with burners not generating .


so you have a yellow flame, not blue?
my mate had same problem. He now uses unleaded, adding 10 drops Redex to a gallon.
He was also told not to overfill the tank - just 3/4 full.
Works much better but he says not perfect.

Coleman propane stove problem


The connector for attaching the regulator to a disposable propane cylinder has a sintered bronze filter in the tip of the brass probe tube that is prone to clogging, or the bronze pellets get mashed down over time, restricting gas flow, and this will cause a portable grill or camp stove to perform poorly. The filter is so fine that it takes very good eyesight and bright light to see that it isn't solid metal, or use of a strong magnifying lens. The best solution is to buy a new Coleman regulator assembly. If you are unable to get a new regulator assembly and have the skills and the tools, you can try drilling a very small hole on the side of the probe tube with a #60 drill bit, just below the bronze filter, but near enough the end of the tube so that the hole will be past the plastic seal when the disposable cylinder is fully screwed into place. You should avoid drilling directly into the end of the probe tube, as the end of it is used to depress the Schrader valve in the disposable cylinder to allow gas to flow. A #60 wire gauge drill bit is only 0.040 inch (1.016 mm) in diameter, but makes a hole large enough to supply sufficient gas to a portable grill or a dual-burner camp stove. If you choose to perform this work, the probe should be unscrewed from the regulator body and the Schrader valve core in the probe tube should be removed before drilling. Be sure to clean all brass and bronze particles out of the probe tube before re-installing the Schrader valve core and the screwing the probe into the regulator. Use a removable-grade thread locking compound to secure the probe in the regulator body and don't over-tighten it, so as not to crush the rubber gasket. Allow the thread locking compound to cure for several hours before attempting to use the regulator. Keep in mind that this modification increases the likelihood of dirt getting into the needle valves and jets of your stove or grill, which can cause maintenance problems in the future.1_28_2013_4_49_27_pm.jpg
