SVEA 123R erratic behavior

Others may have a description. I would say full, but not tight.

 

I like the tight wick theory. Removing a strand just might do it. Ever so slightly loose is better than too tight IMHO.

100% Cotton wick right?

 

Wicks, can be tricky. They need to be a certain thickness and depth. Some work out easily, I’ve fiddled with a few, numerous times even with correct number of strands.

This time, can you take photos of your wick fettling?

SVEA 123R Disassembly


Before disassembly note (mark) where your control spindle lines up with the tank so that you reposition it in the correct place.

Ok, took out wick, removed one strand, reassembled. Fired up, nice steady flame. I think we are on the right track now, the whole diminishing flame effect is gone, in retrospect, it did seem like the fuel was being choked off by a tight wick. May want to take another strand out, still pretty tight and flame isn’t quite as strong as when running at it’s best. Last pic shows the rest of the wicks I got when ordered from Fettlebox, probably generic and meant to be sized to specific stove I am realizing now. Here’s some pics, not sure how this forum will react to posting so many in one post:

 

Six strands I believe is what is needed if I recall.

Can you see my avatar photo?

 

that is what i am looking for

 

Yes

 

This is the best I am getting now with a six strands of wick, would love to get it to 100%, but so much better than before

 

My avatar is an early stove. Sievert Svea 123 with a pin. So earliest model. That makes a difference, but a hotter stove will have a larger flame.

 

Lots of variables, many have their own personality.

I am going to clean it up, reset the pricker and see if I can get an all blue hot flame consistently. What might I try to eliminate the yellow flame tips? Is there a specific depth the wick is supposed to go into the stem, or just bottom it out? Thanks again to everyone for your help!

 

Bottom out, then pull back a little bit. Can't say how much to pull back.
Duane

 

I never pulled back.

 

Whats your flame look like after boiling a pint of water , The stove will get hot enough you will have a hard time touching the font bare handed and that key will brand your fingers if left in place . That is when top output will be apparent . Looks pretty good in the right hand photo . Interesting auxiliary pot stand brackets or whatever riveted to the windscreen . WR

 

Can’t say I have had to replace a 123/123R wick, many others though. Seems the Primus 71’s are the most touchy, one or two Radius 42’s needed a second look.

Yes, good idea. Boil a pot of water. Get it hot.
