i have a new to me svea 123. it was stored by previous owner for 15- 20 years, it is complete. it even has to cup and holder. but was stored with either gas or white gas the whole time it works, but it has major orange tip. i have run a few (2 -3 tanks of white gas) tanks full. i have tried to remove the burner tube using a wrench but my hands cant get great grip(i am afraid to dent the tank.) i then filled the tank with 2 oz of water and proceded to heat the tank(using map). i heated it for maybe 10-30 seconds(afraid to melt the lead) also i did use a wet rag as heat sync but could not get the tube to turn. i have also used penetrating oil to no avail. am i not heating the tank/tube long enough or is there another way. maybe to use different oil i have a primus 210 that i fettled. (burner was bad, there was solder on a large hole so i brazed using my good silvos solder now it runs great.) i know how to heat but am not sure about the lead as i live in the us and cant get replacement parts at a store near me. thanks all for your knowledge and advice
Daniel, the burner thread of the 123 is tapered. Normally tight as on hard to loosen. A 2 sided wrench may strip the corners so what I did was to buy a four sided wrench but forgot the name of the type. The wrench is then placed on a vise and the end of the wrench on to the nut. Holding the tank with 2 hands turn the tank in the direction to unscrew. Most of the time it comes off. I havent heard of anyone breaking off the stem but certainly be careful. When I did that I heard a loud snap and thought I broke it but it just the sound it made when it came loose. Some member might know that type of wrench. Ron
thanks will wait for name of wrench, ( maybe a flare wrench. are they always this hard, or did to gas cause it now i run it and i have a slight orange tip its maybe1/8 of an inch on all 4 sides
Hey Daniel87, my mistake, I was thinking of the Primus 71 I have which had a nut at the base of the burner. The 123 does not have that but you could put the burner in a vise with either a soft jaw or leather being careful not to overtighen and grab the tank and turn it. Just be careful. Ron
Daniel, Others have noted that sometimes a bluer flame is as simple as raising the burner plate a very small amount by fiddling with the tabs. Also, do the orange tips disappear when you place a pot on the stove? I have a few like that and I am tempted to leave good enough alone and disassemble something else for fun.
Mine has orange tips when burning by itself, but they disappear completely when cooking or boiling water with a pot on top. I figure it's OK to just like it is. Stan
Yeah, I think they all burn a bit orange after they're really going. At least mine do. I believe it's trace elements bleeding out of the red hot brass. Nothing to worry about. Some flame shots would be more definitive though. Mike
thanks all i got the tube off there was a nut near the bottom so i used a wrench in a vise and strap wrench on the tank the yellow does go away, but at this moment the burner is puffing as it is burning like a bad idle on a car i will try to move the ring should i try to go up or down i used a mop and thermostat wire to replace the wick, it works better with new wick. the old wick was badly burnt inside the tube, lots of carbon, even with the wick wet it was a little stiff. i am cleaning the carbon out of the tank the tank had gasoline in it, seems like the wick catches alot of the additives. as the tube only had light carbon, i was able to blow through the tube with the adjustment nob open both a lot and little thanks for the help you all are very knowledgeable i love cheap stoves( i paid 20 it was complete with cup handle pricker and the stove even had the addon cap and piston)
i just tried it it runs great it still has orange tips with pot on but i will deal for now or maybe when it cools of, it is 30 degree f here should temp outside matter thanks all
The only time you need to worry is if it starts turning the bottom of your pot black from soot. Then its time to take action. Stan
pump gasoline will make orange flames sometimes. It will take a long time to get it all out of the wick. Your description or a bad car idle sound about right. It was designed to sound like a steam train and if running a very full tank with a slight under prime it really sounds like a train with a little to much on the back with a chuff every 5 seconds or so slowly getting faster til about 5 or 10 chuffs a second. Put a big pot on so it slightly overheats and it sounds like the steam train is doing 100mph with 3 shovelers trying to keep up with the coal use.
if the pot is sooty i assume i need to adjust the spreader. thankfully i is not. i am so happy i joined this forum, i got replies that were to the point. thanks for the help
