    It's been quite dull today but the snow has disappeared, so I unpacked the latest acquisition.
    A Coleman 295, it's pretty tidy but refused to work, stripped down the vaporiser and cleaned everything up a bit, but still no joy, used the ultrasonic cleaner and stripped down the on off valve. After a bit of messing it fired up but pulsed at a slow rate.

    After about an hour it was much better, but I fear it needs a new generator, looking at replacing it
    On the left is my 185 which I bought years agp when littlewoods closed their online service paid less than £20 brand new.
    Both of them do not shut down when the valve is shut, they gradually fade away over several minutes.
    I wonder if that is due to the little Schrader valve failing.

    And why not indeed ? - has the 295 vapouriser not got the paper insert ? - or did that come out before the ultrasonics...
    they both look nice and clean without the usual rust on the tanks

    Didn't find any paper in the vaporiser, but is suspect that someone has been trying to mend it, jet needle is damaged but I didn't pay much for it and it's pretty tidy, so I'm happy, tank is very good with no rust and hood just has a couple of specs on it,
    .
    One on the left is like new with box funnel, and little flint spark device to light it (I've never fitted that) it's had little use.

    Would love to hear from anyone who has experienced the situation where they don't shut down when the valve is closed, the system is fairly basic and seems to rely on a Schrader valve to shut off the fuel.

    @rayw It will be the schrader valve. Do you want a couple ?. I have been there.

    That's very kind, but I have ordered some on e-bay I'm assuming they are just standard Schrader valve like the ones in car and bike tyres.
    I also bit the bullet and ordered a vaporiser, prices for them seems to be pretty much the same everywhere.

    Ah - one needs the ones that are fuel resistant. The normal bicycle/car ones last about 10 mins. The test is to leave one in a small jar of fluid and see if the rubber swells.
    The ones that are rated for air conditioning seem to work. But beware they come in different sizes as well as shapes. I could open a shop with my many purchases... ](*,)

    Ah can relate to that, I have a garage full of bits and spares, so often when you need one item you can only buy ten.
    If you have some spare ones which are up to the job I would be happy to buy a coupl, should save me lots of time and experimentation.

    I think it is rather normal for a Coleman lantern to slowly fade away after shutting them down. The vapouriser (generator) still contains some fuel, and it can only evaporate in one direction! Some of my Colemans can take a minute or 2, ending with a small candle-like flame.

    That's what mine is doing now, but I seem to remember it shutting down much more quickly than that.
    At first when I turn the valve it's as if nothing has happened at all then it slowly starts to dim ending with a tiny orange glow on the mantle, but if I flick the valve open the tiny glow fires up instantl, and its back to full power.

    I agree with @Wim

    @rayw what you describe is perfectly normal behaviour for Coleman petrol lamps & lanterns.
    Given the age of the lanterns, there's no harm in replacing the Schrader valves. Prevention is better than cure.

    Well I dont use them so often, maybe I'll just try to find some fuel rated Schrader valves and replace them whenever I can, as Henry says can't hurt given the age of these lamps.
    When I do I'll report what I find and share it with everyone.

    I didn't have much luck obtaining the correct valve core here in the U.K. (I couldn't see the point in buying a pack of 500) but Mike at oldcolemanparts has these which should work in your lanterns.
    275 Valve Core
    If you choose to try a couple, ordering online is not possible for people outside the U.S.A. You'll have to contact Mike via email.

    Quite a few lanterns have this 'slow shutdown' feature where the 'bubble' of burning gas gradually retreats up inside the mantle until it finally goes out. I'm no expert but I assume it's due to the fuel that's still in the generator when the valve is turned off. The generator is still at operating temperature for a few seconds so any unburned fuel in the system above the control valve will vaporise and continue to expand until the metal cools sufficiently. Most if not all of my Coleman lanterns do this as well as my Veritas lanterns which are somewhat similar in operation.

    I've always found the 'slow turn-off' feature on Coleman lanterns useful when camping. You can turn off the lantern and then you've a minute or two to get yourself into your pit and snuggled down before it goes completely dark... :thumbup: :)

    Yes there is that, but when I leave it in my garage I get the refrigerator light syndrome, just wondering if it really is compleatly out before I release the pressure, when the little 285 lamp was new I used to treat it like the old Tilley shut it down and leave it on the kitchen draining board to cool without releasing the pressure.
    I depressurise all of them now after use, but I worry about letting out Napther fumes if its not srone dead

    A bit brighter today but decided to do a bit more, I call this one variations on a theme, these are all lamps I have bought since my first tentative enquiry in September.

    Left is a nice Optimus 350, middle is the Petromax father Christmas brought, right is a Hipolito I found on e-bay and was surprised to win, still looking at that one at the moment

    @David Shouksmith do you recognise the Optimus, just tidied it up a bit but I may leave it at that, its not quite as bright as the Petromax but not far off which is good considering its 350CP as opposed to the Pmax 500 CP

    Well I wouldn't have so I'm glad you pointed it out! Good to see you got it running so well... :D/

    Nice trio - I think an earlier Optimus 350 model ?

    I believe so, but I'm a relative newcomer and no expert, but I understand that this one with the fuel level gauge but no pressure gauge is one of the early ones, I did a few bits to it and cleaned up the vaporiser, I also made a slight modification, . Optimus 1350 knowledge needed

    but it seems to work pretty well now, and it seems to be much more economical that the petomax even allowing that it is a 350 as apposed to the 500.
    I think this is one of those lamps you could use regularly and it would be reliable.

    Oh yes - I remember the other thread now... old age and infirmity creeps on - or is it lockdown fever...
