    Early Lamborghini, Jarama, according to the OM the firing order is 1-7-5-11-3-9-6-12-2-8-4-10. But the firing order looking at the markings at the dizzy cap, (which is a Magneti Marelli, and probably original), has the following firing order, looking at the cap and run CW,
    1-9-4-11-2-7-6-10-3-8-5-12.

    It doesn't correspond to anything!?

    I still don't get it, because if I look at the dizzy and note the cylinders CCW I get;

    1-12-5-8-3-10-6-7-2-11-4-9.

    The numbers on the dizzy are not cast in the dizzy but small round labels printed with the number, just as early ferraris had.

    I think the confusion is from the 2 coil system.
    Take a look at the rotor The next cylinder to fire
    is 180 degrees off. ???

    Yes, of course. I should have looked inside the distributor and not only from the exterior. As the rotor is a "two level" rotor it fires alternatively, thus my confusion.

    Firing order and cylinder numeration in the OM is correct.
