    Forget carb cleaning need updated carb

    After all my research today, it appears that the older style carb pictured has a 3 adjustment screws,
    The jet needle pilot adjustment screw which Mikuni did away with in the early 90's, and a low speed and high speed needle jet adjustment screw,
    the newer SBN44 carbs just have the 2 adjustment screws and the square pump instead of the round one, thus more fuel pressure, and better design,

    I am now in the market for a newer that 87 mukuni SBN-44 carb,

    The jets on the one I have were way off, the low speed jet was 3 turns out the highs were turns out and the middle or pilot jet wasent to bad at 1 complete turn out,
    Until I get an updated carb, does anyone know the correct needle adjustments from the factory???

    and if anyone has a SBN44 for cheap let me know??
