    Hello everyone,
    I’m a new member and also new to pressure lamps, so please forgive me if my questions sound a bit basic.

    I’ve recently started working on my lamp and I’ve taken apart the carburetor with its gasket. I found the small needle inside (I believe it’s part of the cleaning system?), but now I’m a bit stuck.

    I would like to clean and check if everything is working properly before I put it back together. My questions are:

    1. What’s the right way to use that little needle? Should it be inserted in a specific direction or checked in some way?


    2. How should I clean the carburetor and gasket without damaging them?


    3. Is there a simple way to test if the system is working correctly before I reassemble everything?



    Any advice would be really appreciated. I’m just starting out and want to learn how to do things properly.

    Thanks in advance for your help!

    Welcome to this forum. It would help if you tell us what lantern you have, name, model, pictures also help.
    Looking at the parts it is a Petromax style lantern.
    It is crucial that you read and understand the workings as well as safety rules.

    Thanks, everyone!! I’ve tried to repair it and give it a test run.
    The lantern is a Petroflam (Italy) 200 hk. There are probably still a few things to sort out, such as getting a suitable glass globe.

    The combustion is a bit odd: the mantle doesn’t glow properly, the flame is yellowish and escapes from the mantle; at the top of the chimney, the flame even turns almost green. I also tried using it outside on the terrace, and thanks to the wind the mantle glowed more and the combustion seemed better… why would that happen?

    I also think there’s an issue with the needle: the valve doesn’t fully close, making it very hard to regulate the pressure and flame flow. What do you think?

    My guess to big of a mantle.
    Second; I am pretty sure that in the documentation I mentioned it states that the hand wheel operates or can operate the foot valve in the fuel pick up tube and the cleaning needle.
    You can not adjust the light output with it.

    200Hk parts are not available any more. Nearest would be 250cp it the thread sizes match.
    Which may also include the globe.
