    This is my most recent acquisition - a Petromax 829 Rapid. It came via rik_uk3 of the stove site, so a big thank you Rick for for this lovely addition to my 'P'Max' family. It's actually the first genuine Petromax I've owned!

    It's very interesting to note the differences/similarities between an original and the various clones, even though this particular model was actually made in China.

    It needed some adjustment and it's still not perfect just yet. It's running rich despite a quick tweek so I'll have to increase the air gap even more. I suspect there's a slight leak, maybe from the rapid preheater so that'll need looking at as well, but it cleaned up extremely well.

    Cor blimey Colin, you’re not handing around. Is it a new lamp daily or weekly?

    Great lamp!

    @ColinG Nice lantern. You will enjoy the comparison more with a original Petromax - the difference is significant. New to the game, I started earlier in the year purchasing a brand new Petromax, (made in China), struggled to get it to work, it took some fettling. In my quest to get it to work I ended up getting bitten by the bug and some research from here got me in to earlier Petromax's - my experience is that they work much better than the "new" Petromax and are of a far higher build quality. Having said that, my Anchor 500cp is a star and of far better build quality than the new Petromax. All said, they are great lanterns.

    Hmmmmm, I'll post more later, but I'm beginning to re-think the quality of later Petromax models. Just had to go through hoops to fix what should have been a simple problem. Still glad I have it though as it looks gorgeous!

    I have an anchor 950/500cp and so far it's an absolute dog of a thing. I must have gone through 5 needles and only 4 light ups. it bends them all the time or they have gone after a light up.

    I light it with the spiritburner, always twice before turning on the tap
    It flares up like a nuclear detonation every time, then massive flame corona and then if I am lucky it settles and runs.

    What am I doing wrong? or is it just a dog of a lamp?

    It's really hard to tell. It could be that you have a Friday afternoon job that's never going to run properly. I'd check the air mix by widening/lengthening the j-tube gap above the jet which should lessen or stop the burning halo around the mantle. If that doesn't fix it, the jet could be worn, in which case you can swap it with a new one which can be bought very cheap and you might even have one. If not I could pop one in the post for you.

    Another thing to try is winding some copper wire round the pricker rod to help vaporise the fuel efficiently.

    Hope this helps.

    Cheers @ColinG,

    I do have a spare jet, so I'll give it a go, and thanks for your kind offer. I'll try a bit more adjustment and the copper wire fix. It might line up the pricker needle as well to stop it always bending.

    Oh, and if yours in the same as mine, the rod can be adjusted up and down to alter the position/height of the needle. If you fiddle with it, you'll see what I mean but basically, the rod screws in and out and is secured in position by an adjustable nut.

    Thanks Alex,
    Compared to this display, my one Tilley 246b feels like single child.

    Love your collection of P'max and P'max clones @bp4willi - they do make a very shiny display!

    Since my last post I've discovered a problem, fixed it but there is still things to be sorted out. The spring mechanism that holds the pip over the rapid preheater jet had a very weak spring which was allowing fuel to escape albeit a very small amount. Additionally the pip was hard and needed replacing. However, when I tried to prize the pip out, the brass tube disintegrated! Until that was fixed the lantern was unusable so I managed to fabricate a replacement with parts borrowed from an old NRV. That seemed to do the trick, but the spring is just not powerful enough and I think a tiny amount of fuel is sleeping out although this needs to be confirmed. If anyone has any idea how to replace the spring let me know because it looks pretty hard to do and maybe impossible!

    So... my current opinion of Chinese (11 pointed star logo) Petromax models is not great. Mine runs but it smells a little whereas other very similar lanterns do not.

    Two of the Px are from 50/60ies.
    Three are China Px.
    All work fine.
    But I admit, Px need more fettle at start, than Coleman or Tilley.

    That genre of lanterns usually work well once they have been properly set up.

    I wonder if anyone might have a donor 'kipphabel' in their collection of parts?

    I regret. Don't have.
    Never needed one.

    @ColinG , can you post a picture of what you need ?
    From the story I don't get a clear picture.

    It is this part. The spring is very weak and the rivetted mechanism is poorly made.

    I looked through my stock and found none. Like said tehy normally last forever.
    I found them online for around 8 euro with the blue back instead of the full metall back.

    The Basecamp one is a complete unit and it isn't for Petromax so if might not fit. The starlichtlampe site has the one I'm going for... I've asked him to get one to save a bit on postage. Thanks for the heads up.

    That usually happens when the upper vaporiser and/or conducting rod is bent and the needle does not float freely in the exact center of the tube.
    The conducting rod length may also need to be adjusted so that the needle does not protrude through the jet by more than 1mm, ideally 0,5mm.
