you think that's a time warp check out the how i became a stovie thread 25-11-05 03:23 PM and the next post 08-09-09 02:28 PM 4 years
I have one of these, the thread for the burner is stripped but i have a friend fixing it, hope i can it back to life again, should be able to.
They are obviously common here. Mine will crank out the heat as well. Have to agree about how hot the tank gets. Mine has a small leak in the filler cap and the vapour coming out once hot will frequently ignite causing a little pop then go out then ignite again.Also the pump handle gets too hot to touch. Dont know why they run hot the burner is a long way from the tank
I'm just refurbishing one of these at the moment. The tank appears to be steel rather than brass though. I am missing the flame spreader unfortunately. Needs to be 41.5mm max od & 37.6mm max ID if anyone knows where I could get one please? Presuming that the storage tins were painted the same as the stoves? Bit hard to tell now. Steve.
On mine there is no hint of there ever being any paint. The inside is tin plated so Im guessing it was fully tinned at one stage but now its mostly surface rust with a kerosene glaze. One thing to watch while storing these stoves is that there is no way to seal the jet. If you do up the air bleed screw then temp variations will pump kero out of the tank over time. I have on occasion found more fuel in the tin than the tank. These may have been Britons answer to the m1942 and m1950 but they are not a pocket stove.
Hi Parramethrol, You mention fitting a new jet ... did you just unscrew and clean the existing our or source a replacement please? I am just about to clean and rebuild the same stove. Thank you, Tim
Hi @Onfire Tim That is the resurrection of quite an old thread! OP doesn't seem to be around here too often these days, so I can't answer with any certainty your specific question of whether it was remove, clean and refit or remove and replace. My reading of it was replacement with new. It is a little academic as the state of his stove jet is likely to be different to the state of yours. These stoves had the patented Townson and Coxson burner with the central "access hole and bung" screwed into the top plate which, when unscrewed, gives access for jet removal directly from above, using the service tool contained (originally) in the spares pack. This simplified jet servicing as it obviated the need for side access with an articulated removal tool with like a universal joint as you might need for replacement on a stove with a conventional roarer burner. So, my next question is - does your stove come with the shallow round service kit, which would hold spare jets, various seals and washers, the service tool and a block of lighting powder? If so, happy days, and you have a spare jet or two and tool for a quick replacement if needed. If not, a flat blade screwdriver will remove the bung and a standard jet remover for a silent burner stove will likely need grinding or filing down a bit around the socket end in order to clear the smaller hole in the burner top plate and access the jet. The tool /spares kit can be seen in the thread Bring out your Hurlocks To clean or replace? I would look to clean the jet but do bear in mind that they can wear and so burn rich with a floppy and yellow tipped flame, which indicates incomplete combustion and production of carbon monoxide - a potential killer in enclosed spaces. On the other hand, replacement is only an option if you have a suitable spare! Jets come in two hole sizes which generally depend on the capacity of the stove (1/2 or 1 pint) has the small 0.23mm jet hole, larger (2 pint plus) tanks have a larger 0.3 something mm sized hole. Jet threads are generally all interchangeable between makers, but if you want originality, a Burmos 21 stove would have been made by the same company .... Let us know how you get on, pictures of the stove running are always welcome.
Hello @Dean , thank you for your reply, especially on such an old thread. I had wondered if the OP had sourced a replacement burner. I do have the spares tin but it has only got the screwdriver tool, a number of old washers and lots of pricker wires; no spare jets. I have soaked and scrubbed my stove. It was pretty badly sooted up, but i hope not too much carbon on the inside. I think mine looked worse than it was with mould on the sooty build up around the burner and windshield. I rebuilt it with new seals and then had a test fire outside. It began well but a strong gust of wind blew the flame out between priming and full roar. I will run it again when I get chance on the weekend. I'm so far pleased with the clean up, hopefully well enough but has retained the patina. Thank you @kerophile - I hadnt considered the crossover to Burmos or other burners. I was interested to find a B on the burner nut, Burmos perhaps?
I hope you won't mind me correcting you Dean, but the vast majority of paraffin stoves used a nipple with 0.32mm jet size, from one-pint models through to two-pints. Biggies went bigger! It was the half-pint lipstick models alone which used a 0.23mm orifice. Some petrol stoves used a 0.23mm nipple, which are hard to come by now other than by the sleeving methods well known and documented on here by the inventor. Some Birmingham-made one-pinters were also fitted with 0.23mm nipples during one of the fuel shortages.
That is really useful @Blackdog thank you. Do you know of a supplier for new / old jets please? Mine is burning quite orange which I assume to be down to a worn jet / nipple
@Onfire Sometimes the flame will clean up with use- fresh fuel may dissolve old deposits inside the tank which affect the flame until gone. But still quite likely a new jet is needed, and if that fails, a burner decoke. Base Camp sell jets, or have a look on ebay although I believe quality can be a bit variable with these. Edited as posted at same time as Kerophile- I would have suggested fettlebox but they've been out of stock for a year or more.
