NEED Help with Whisperlite International Stove

[Rainman]

Well, got it back today $37 charge. They did not tell me what was fixed and it is supposed to be lifetime warranty!

[Rainman]

Well whatever it was, it is already being shipped back to me as a warranty repair. Should have it back later next week. Casade Designs moved fast.....

Yeah, i love my whisperlite and have problem solved just about everything on it, but the only idea i had on this was overfilling. Sounds like u have some type of pressure leak, i think returning the whole thing sounds like a great idea...

Oh well. Slightly disturbing because I always thought mine bulletproof and easy to fix. It's gotta be something simple that just isn't jumping out.

The stove is totally clean. Yes it will relight when hot as long as I pump it. Spoke with MSR and they had no idea. It is on its way back there to them today. I will switch to an alcohol stove also until it is back. Easy enough to make one. Thanks for the ideas.

I have never seen one of these and can't find a suitable picture of the parts that go into the fuel bottle. Is it possible the fuel pick-up line (assuming it has one) has been bent and is positioned above the fuel level and the hissing is the compressed air in the bottle?

Nice picture. Substitute dip tube for pick-up line and make sure it is opposed to the valve so as to be submerged when bottle is horizontal. It was stated there was no fuel with the air hissing out.

I went camping with a friend who used one of those stoves. By the time she got done fussing around with it and got it lit, I was handing her a cup of coffee prepared on my MSR Pocket Rocket. Hers was too much of a hassle for me. My solution to your problem would be switch to a canister stove.

Off topic but I've recently switched to alky for the warmer months. I LOVE IT!

Fuel is easy to get, and cheap. The stove is light, relatively compact and bulletproof.

I've used canisters before and I have a whisperlite and I don't plan on going back to my MSR unless I need to go out in the extreme cold or high altitude. Alky is simple and effective and the Trangia stoves are fairly quick to boil water.

I should have switched years ago!

PS pump looks like this:



Doesn't make sense it would be in the pump assy if it gets fuel cold and not hot - if it is heat related, it has to be in the burner, fuel tube, or jet area.

They will hiss if they have been primed (sufficiently to vaporize the fuel in the delivery tube), turned off and then the fuel turned back on without lighting. The hissing is normal and is the vaporized fuel coming out of the jet.

You can relite these when they are hot usually without re-priming. It will hiss with vapor and putting a match to the burner will pop it back to life.

Do you have to let it cool down and re-prime it before you re-lite it? Or will it re-lite if you pump it again.

I The pressure bulids up and the stove continues to hiss even though it goes out. For some reason the fuel does not continue to flow with the air. The fuel is new Coleman white gas.

FWIW the air for the mixture doesn't come from the line. It comes from the atmosphere and mixes at the burner. Liquid fuel will not come out once it has been primed and warmed, just vapor (or air as you are calling it). That mixes just above the jet and burns.

Could also be a thermal expansion issue at the burner - did you remove the burner hood screw and clean out the burner? They don't mention that in the maintenance but it is worth a shot...

[Rainman]

Thanks for the feedback. I am not overfilling the bottle. The stove lights easily and there is good pressure. It even "roars" when it gets going, the pan glowing red hot. Then it just goes out. You still hear the air pressure, but for some reason the fuel stops flowing unless I keep pumping it. I think I am packing it up and sending it to MSR.

Good point. I'm a cold weather wimp, so didn't think of that.

I use the pocket rocket in the warmer months for the reasons stated above. But canister stoves perform very poorly (or not even at all) in the winter, so I stick with my trusty whisperlite for the colder months.
