That's in lovely restored condition, I do like that red colour ,it looks good on it, I might even paint one of mine in red later this year when its warmer outside. Regards Ian
The seller says that it's been fitted with new seals and holds good pump pressure but hasn't been tested.
@Sammi Jane it might be worth testing your new lamp without a mantle before fitting a mantle? You can get a good idea of the condition of the vapouriser by the colour of the flamelets.. nice and blue = blue with quite a bit of yellow @Tony Press has a whole thread on this very subject
The lamp arrived this morning, so I'm going to give it a test lighting today before fitting a mantle.
Well, I've just tried lighting it and the results were disappointing to say the least. There's quite a big leak from the control cock, and there's not much in the way of a flame and it's all yellow. @Jean J's other half is going to have a shufti at it for me on Sunday.
I can imagine your disappointment. Hopefully the leak can be cured by tightening the gland nut. It needs to be tight enough to not leak but loose enough to be able the control knob back and forth quickly. Usually, but not always, yellow flames mean the vapouriser is shot i.e. the orifice has become enlarged and is letting too much fuel through. Have a look here :- 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.
We're just back from getting the lamp fettled by John, and the test lighting was successful. Thanks @Jean J for your help.!
I've now got the shade for the lamp, and here's a picture showing it with and without it: Apologies for the blurred picture
The lamp does seem to lose pressure quite quickly, and I'm not sure how to check to see where air could potentially be leaking from...
The problem was the NRV, but after changing the washer in that it's working as it should. Thanks to @podbros for the diagnosis. I've got another question though, what's the little pip on the top for.?
Hi @Sammi Jane The part you are referring to is the pressure nipple or “tit” as it is more commonly known. Sometimes they work, sometimes they don’t and sometimes partially. The idea being the internal part will be flush with the external when at full pressure. I usually stick to the instructions which came with my first and only new X246B which I purchased way back in 1992, which state something along the lines of 10 pumps to light followed by another ninety once running to take it to full pressure. Some happy reading here for you: Tilley Pressure Nipple gauge Enjoy your new lamp! Regards, Jeremy
