    I have bought a pack of BGM carb needles for my PWK carb and on the needles are letters:

    JJK
    JJL
    JJM
    JJN
    JJS
    JJQ
    JLJ
    HJK
    KLK
    HLJ

    other than measuring the taper etc which there are only thousandths of a inch between them can anyone shed some light on which order they go in from lean to rich?

    just want to be sure which ones are which.

    Thanks

    I rang the shop where i got them from and they didn't know and suggested emailing BGM in Germany which i did . The fella was very helpful and sent me a excel spreadsheet with lots of figures and numbers and charts and couldnt make head nor tail of it, so none the wiser lol.

    the longest thickest will be the leanest.
    the shortest thinnest will be the richest.

    now go get a micrometer
