    Hi, @Tantra What do you men by "chock" in the central tube?
    it does not make sense in English.
    Can you post a photo?
    Do you mean a crack or slit perhaps?
    Best Regards,
    Kerophile

    I am pretty sure that choke ‘washer’ should not be in there. Can you prise it out? If so, take it out and try with conventional inner and outer caps.

    Hi @Tantra. As Twoberth says,that should not be there. It will reduce airflow and make the mixture fuel-rich.
    Remove it and you should get an improvement.

    A bit of lateral thinking, could they have been trying to run it on meths/spirits?

    Good idea
    In my mind a unregulated silent burner use alcohol not safe
    I have never seen any case
    I found the tank very dirty not same to Meths spirit
    Also not any sweat smell
    The jet is normal size about 0.32 mm

    maybe modified to run with out burner plate or cap as the washer would act as a flame holder to the jet of gas coming from the orifice? just an observation

    I flow the some US master suggest,Yes it’s was use ethanol,and use original 0.32mm jet,works fine,flame not big but very stable and reliable.long times work not make tank hot even use 1/2 pints small tank,such as Primus No.210
    Can not pump more than 8/10 times,flame will fly.
    No reflux Noasthma.
    Amazing discovery to me
    I can imagine the burner was designed in world war two
    He fire 15 minuets can not make a trangia 0.6 lite pot boiling.
    At last 18 minuets
    That’s mean thirty minutes one liter water
    Now the tank temperature about 30
    Maybe I have to try 0.5 mm jet
