    I just bought an assortment of unmarked regulated burner jets and needles. The seller said that as far as he knew they were all spec'ed for paraffin burners.

    5 of the needles fit 9 of the jets. 3 (used) jets are too small for any of the needles.
    The remaining 13 needles are only just too big to fit the 9 jets and definitely too big to fit the 3 smallest jets.

    Can anyone please cast some light on this conundrum?

    Is the jet and needle size of e.g. a Primus 535 burner different from that of an Optimus 11 or a Radius 43?
    I admit I'm not familiar with the various burner model numbers.

    Hi @phaedrus42
    To attempt to solve your problem I suggest that you provide some measurements. Do you have a micrometer to allow you to measure the diameter of the cleaning needles?
    Once you have measurement of a needle you can try it in the jets and estimate their diameter.

    Best Regards,
    Kerophile.

    @kerophile , Thanks, I'm sure I can measure a few needles with a borrowed one and work it out from there.
    I have enough stoves to make a useful comparision, I hope...
