Best to do a dunk test first to check for air leaks.. bucket of water Before you put fuel in You only need to immerse past the control cock as air will always leak out of the vapouriser Give it a good 50 or 60 pumps then dunk in if you are happy then read up again on the instructions that Mackburner posted as i find it always helps to refresh I always put a bit more oil on the cup washer.. 3 in 1..
pb, I tighten her up and the pump is working as intended but she won't hold pressure she seems to he failing at the control area and when I put the vapouriser on I'm getting an extremely fine and gentle stream of air so that's working well, any idea on how to fix it. Cheers
pb, I've done the test and there seems to be a couple the 1. The Pump which had a steady stream of bubbles 2. The Filler cap but it near enough stopped once I tightened it a bit more 3. The Control knob a bit was coming out there but that might be too submerged. As I'm unfamiliar with how sealed it should be has it passed the test there was still air coming out of the vapouriser when it was submerged to the control tap. Cheers
Hi again @Balach Mor Sorry been doing stuff and forgot I was still logged on 1. If it’s coming up the pump tube then a) the nrv pip (inside the nrv unit) might not be seated? or b) the washer sealing the nrv unit may not be sealing to the bottom of the pump tube? I remember you saying there was the remains of washers down there.. did you make sure to clean them out? 2. Filler cap .. hmm.. check for dirt etc 3. Control knob.. was the main washer to tank leaking or the gland washer? again if all is clean then try turning the control unit and if it’s the gland then gently use a spanner til it stops? perhaps other members might have more insight here?? The nrv ‘pip’.. make sure it’s level, not canted over The nrv washer goes here
pb, problem was I put the NRV washer in the wrong place sorted it and replaced the rest of the seals and there was not a bubble here, there or anywhere!, I think she is ready for the next test!. Cheers.
Ah ! Well done , you sorted it thats great!!! yes, I know that seals can ‘feel’ ok but it’s just so much easier to just replace them all and you eliminate all sorts of potential niggles.. all hindsight but we have all been there Really good you have sorted the air leaks as it can be a plague later on, especially if you have gone to paint etc etc then have to handle everything and of course the finish suffers Good for you ps I’ve done the same, then got distracted, gone back to it and forgot which seal I replaced.. nightmare
pb, Yes I thought that I might as well replace the rest of the seals. As for the burner I blew the dust out of it anything else that needs done to it?, cheers
@Balach Mor Ok , that’s good Will you be doing your test fire indoors or outside? If you have somewhere out of the wind, i would advise the latter as at this point I would be testing without the glass as it’s easier to get at the meths tray/wick.. you will probably need two pre heats Have you put the cage/frame back on yet? If you have then also leave the hood on too but take the glass out and keep safe, Have a read of the lighting instructions that Mackburner posted as it will say about what to do with a possible ‘flare up’ Good luck and let us know how you get on edit : if you get a flare up quickly undo the pressure relief screw on the filler and if the meths has gone out then preheat again
@podbros, I've tried the burn test I probably put far too much Methalyated Spirit in the cup and wick!, I also think I pumped to much before she lit as you'll see I released some pressure a couple times but I did get nice blue flames, any good?
When testing without a mantle fitted only a small amount of pressure is required, your lantern is progressing well.
Hi @Balach Mor Great that you got it to work but I’m not entirely sure that your vapouriser is ok? let’s ask more experienced fettlers for second opinions if that’s ok? @JEFF JOHNSON @Henry Plews @Tony Press @steerpike451 @Gary Waller And all welcome!! (alphabetic order)
You are welcome. Balach Mor The vapouriser may be okay, in my opinion, the only way to be sure is to fit a mantle and test it.
An obstruction in one of the air vents, along with over pressure can result in a rich mixture, hence the yellow flames. Unfortunately if I were to nail my colours to the mast earlier I would say the vaporiser jet is enlarged and allowing too much fuel into the burner. If you had a spare hood / burner from another lamp you could switch them to help confirm either way.
@Gary Waller, as this my first Lamp I haven't got another lamp and I dont know of any locally I could borrow, I did hear a kind of light pop/thuwnk noise as the as the burner kicked into motion It must have been gunk stuck that I didn't get out, I did try the burn test again and this is what I got. Is there any fix at this point or will it run with a mantle albeit at a reduced capacity?
1: a pop as the vapour lights is normal. 2: as Pod said, that flame shot actually looks pretty good. 3: in the first photo with the yellow flames I can see that the hood is not fully down, which will affect the mix adversely . Try it with a mantle and see what happens!
@@steerpike451, The pop wasn't the vapour lightning it was more than it and only the first time so I think I did a poor job of clearing the burner but it seems clear now, You are right about the hood being up slightly it wouldn't catch alight when I pressurised it so I moved it up and it did catch but as you can see bad flames the 3rd photo is with the it down and with lower pressure, I think there might still be some remnants of dirt so that could be making it more orange because it is sparking ever so slightly from time to time, the last photo is also with lower light so it may look better than it actually is but I do think it slightly bluer than the 3rd picture. Cheers.
I reckon that will be OK with a mantle. Like others above have said you can put the proper pressure on that, which should result in lighting nirvana...
Hello everyone I think it has failed the mantle, I don't think the mantle burned correctly it doesn't light up at all really just a couple spots like it should be, any fix?.
@Fireexit1 I've tried again at 50 pumps, the tank isn't full it's about half full, it worked a bit better than last time but still poor should I fill it up fully?, but after I switched it off the mantle looks very blackened with only a few white spots remaining, cheers
I think Jeff is right. You have fixed/cleaned everything else so all that is left is the vapouriser. Some searches here in this site will give advice on tips and tricks on reviving them, but this is not always sucessful.
@Balach Mor Bialaddin and Tilley vapourisers are more or less the same so here's a little trick that's worth trying, after all, you've nothing to loose. Tilley X24B was fine, now not burning correctly = help please. I later edited that post, Check that the cleaning needle still shows through the jet, it should be a very close fit and a jewelers loup or good magnifying glass will help determine how effective the piening is. Keep dropping the vapouriser and checking with the magnifying glass until you're satisfied with the needle/ orifice clearance. Test the vapouriser in a lamp. If it still behaves the same, repeat the process but only drop it once before checking that the needle clears the jet. Incidently, the needle diameter is 0.007" / 0.18mm so the orifice is going to be in the region of 0.0072" / 0.18+?mm And from another post, I forgot to mention, save yourself money by not replacing the mantles unless they have holes. Any soot deposits will burn off once a correctly functioning vapouriser is fitted.
