My Svea 123 that I've trusted for many decades is not well. When test priming it today to prepare for an excursion into the cold it became a growing fireball! I had to douse it with water. Thank God I was not in the backcountry or I would have set the woods ablaze! There must be fuel leaking somewhere. I do not have a workshop. I do not want to disassemble my old friend willy nilly. The forum threads are many and daunting. Any advice?
Thank you for the comments. I went back outside after allowing the stove to cool. There is fuel all over. Took off the windscreen. I equalized tank pressure by removing and replacing the fuel cap. I held the stove in my hands to use my hands warmth to pressurize the tank and see if any fuel escapes I can see. Amazing, the fuel is seeping out the pressure relief valve. There must be a capillary effect as there is only a little fuel left. So now the questions are why has this happened and what is the solution? Is this from too much primer? Blocked flow in the "generator" creating backpressure? Is it as simple as replacing the fuel cap?
More reading...perhaps a dried gasket issue, which some brilliant youtuber mad from bisycle tubing!. The pressure relief valve is the current unanswered question of what to do. It seems it must be replaced?
Robert This thread will show you the components of your stove. You may need to replace the pip in the Safety Release Valve (SRV). Svea 123 Disassembly Check to make sure it’s that component that’s leaking. Best regards Tony @Robert Burke
If you don't have a Optimus pump, you can place the fount in the freezer for a little bit with the valve closed and fuel cap loosened, then when chilled enough, tighten the cap and dunk in hot water and observe any bubbles. Duane
