Hi, I've been playing around with a new-to-me Canadian-made Coleman Solus and done a quick cleanup on it: placed the burner in an ultrasonic bath. The washers, cap gasket, and jet have been replaced. The jet I installed was from a monitor spares kit. Before I replaced the jet, it had problems with flames going out and occasional flaring with big yellow flames blackening the side of the kettle. Plus, I had to periodically use the jet cleaner, otherwise the flame would eventually become weak and off-centered. I thought the jet was the problem. After replacing it, the flaring stopped but the off-centered flame still happens after several minutes of running. I'm doing pre-emptive pricking just to prevent it from occuring. Worse, It now has a problem keeping the flame lit at startup...at times, it seems as if it's just air coming out of the jet. What should I try next? ps. I've also tried letting the stove burn a full tank of fuel.
What you really need to do is send it to me. I'd love to get my hands on one of these. Now on how to fix your Solus, it sound to me like it may have a fuel pickup issue. Do these have a wick in them ?? If so, I'd have a look at that. Either that or just send it to me. If you never see it again, its because I am still working on it
Burners still full of burned up kero carbon residue , you need to heat & quench it in a citric acid solution a few times to rid yourself of this problem . Take the jet out first though this will allow the steam generated when quenching to flush the loosened carbon out , but may take up to ten times to get the worst out then blow through with an airline Heat the burner with a propane , kero or petrol blowlamp until dull red , do this in a darkrened room so you can see the colour & with a bucket of cold citric acid solution to quench the burner in next to where you do the heating up , the carbon is loosened by thermal shock Use tongs to plunge the burner into the cold liquid when a dull red is acheived , & be careful as a lot of steam can be generated plunge the burner in so both inlet & outlet are under at the same time Best regards Stu
weasel, Thanks for the suggestions. I've pressurized the tank without the burner and a good stream of fuel shot out, so it looks like the fuel pick up is good. I've tried the heat and quench but would like to give it another go: I don't think I was heating the burner enough and plunging it in the liquid quickly enough. I've also tried looking at how the stream of fuel shoots out of the jet and it comes out at an angle. Did the same with the old jet. The new jet I'm using came from the Monitor spares kit... Is this the correct jet size for this stove, btw?
Hi, The Monitor spares outfit jets apertures are 0.32mm diameter, which should be the same as the jets of the Coleman Solus. Best Regards, Kerophile.
Problem solved! Thank you. I did another session of "heat and quench", done properly and that eliminated the off-centered flame. The weak flame was being caused by a defective jet that was made with a shallow bevel at the orifice. I swapped in the other jet from the Monitor spares kit and the flame is larger now.
I received the stove as a trade for painting someone's Preway stove. It was missing the flame ring and preheat cup. The flame ring is from a Butterfly stove and is made of steel so it doesn't glow as it should. Here it is when the flame was off to one side. Larger flame. Some yellow at the tips but I'm ok with it.
