Svea 123. Not enough pressure?

There are some strange advises in the net, what to do when travelling by air, with a stove. Some days ago, I have read to fill the fount with salad oil! If there is a unsuitable liquid in the wick (even water) it will not work properly any more.

Where can I get the pentagal wrench. Or what ever it's called.

 

I would not light it without a jet.

That is a problem.

Long debated here. Many threads about that.
Make one is the easiest way.

Sometimes a good tool is up on eBay made by Varga???.
Do not use the quietstove tool. It will damage your cap.

 

I have a 1966 SVEA 123, and I can tell you that sometimes it runs amazingly well, and sometimes crap! I have taken out the wick several times to check it, and found nothing of note. It always pays to prick the jet, and maybe ream out the jet opening (very gently) with a drill bit (1/16) to get a good flame.

Hello @Quick Cal . That black blob indicates to me that you may have some type of foreign residue in the wick that dissolves as the fuel passes through and then collects at the jet aperture or the original wick may have been replaced at some stage with another that may not be 100% cotton and may contain polyester.
Try replacing the wick with one that is known to be 100% cotton. John

 

Do you drill the hole out to .062" (1/16") or do mean cleaning the top of the hole?

You may have a foreign substance that using it might clean up. Or replacing the wick might be needed. I would use it A LOT and see if the problem persists.

So I've ran it 6 or 8 times after flushing the vaporizer. I lit it with out pricking. Seems to be working fine so far. Thanks for all the help.

 

Good news.

 

Now that you've got 'er going, another useful tip: on the trail, when you've finished cooking dinner and the stove sits overnight, open the fill cap to equalize the pressure, or it won't work.

Most times you'll refill before then but sometimes not. I had to learn that one.

 

Hiya Team and Mr Snow Camper,

I use the drill bit to gently clean out the top of the jet, and not to go right through the jet. I suspect that pricking sometimes leaves a small burr, which distorts the flame pattern. The flame appears lopsided or wonky, and a gentle ream, one or two gentle turns of the drill bit remedies the problem.

Very good. I took the word ream literally.

 

I have to say I've never had to "prick the jet" over the course of many years on my Svea, though I sure wouldn't want to be caught in the field without one, because there is No Substitute, not as a practical matter. I keep one filched from an MSR taped to the underside of the tank. A light gauge high "E" guitar string will work in a pinch.

 

I have pricked the jet on mine in the field, but very seldom. If this was my stove I would be pulling wick, I would never trust it out in the woods. A stove that I have to mess with before I get me hot coffee or dinner is not welcome in my camp.
