Hi I have a buddy on the StovaHolics FB group who's struggling to clean a vapouriser on his lovely JC Highins double burner stove. I normally heat and quench but the vapouriser has an additional tube attached I think by solder. Anyone know anything about these stoves, how best to clean the vapouriser and what it the additional tube for??
@Robert Radcliffe If you scroll through THIS thread in which I featured my three-burner example of one of those you’ll see a post by @shagratork in which he focuses on the vapouriser, including this schematic and a link to a patent. It won’t be lead solder on that tubing but will be silbrazing to cope with the heat. With some restraint and care it could cope with being heated up in a blowtorch. Blowing out the loosened carbon with an airline would complete the job. Whether that would improve matters depends on how coked-up it was by pump gasoline in the first place.
@presscall Thanks John that's a great help. Should have been obvious it wasnt solder, doh! But ultimately good news if he can try a decarb. So it's a kind of fuel filter.
That generator was marketed so the stove could burn pump gas as well as Coleman Fuel (CF). In the early version the large tube was serviceable, your version isn't. When the large tube got clogged you were expected to replace the generator. Another model of the stove was identical except that it had a conventional generator and was designed to run CF only. I'm willing to bet you could find a Coleman generator that will fit and switch over to a CF only set up. I'd start by looking at the 425 or 413 generators from the same time period.
