    Hi,

    Does anyone know what the jet size of the standard 1200 and the 1200B is? I've looked around, but can't find a definitive answer.

    Thanks,

    Ellie

    Is it not the same jet as the 200 and 200P? 0.16mm sounds right as 0.2mm is 300cp

    You might find this table from Lahde's book handy. ::Neil::

    The PX 250 is 0.17mm but I've never been quite sure about the Optimus 200cp jets, 0.16mm would make sense, but that doesn't jive with the table Neil just posted.

    The 1200B jet has a different part number to the 1200, so are we looking at a difference in orifice size or perhaps something else?

    1200B is a petrol model.

    Hi, yes I know, I need the jet sizes for both the kero and petrol version of the 1200.

    I have 0.16mm orifice listed for 250 HK in kerosene and 0.17 mm for 200CP
    Sorry I don't have a listing for 200 CP gasoline.

    That is a very useful table, Neil!
    For Optimus 1200B (petrol), I suspect a Px 250cp jet would be spot-on. An Optimus 930 300cp jet would probably also work just fine.

    Thanks everybody,

    I guess some trial and error is needed.
