    This is the sequence I use:

    When you pull of the intake you will find one of the combinations listed on the left. If you find an “a” set opened you use all of the “a” sequencing. If it is a “b” use all the “b” sequencing and so-forth.

    Hope this helps.

    Tom



    Sequencing:

    Valves Opened - Adjust these

    a) 4X -- 1N ---> 3X- 3N- 8N- 6N- 7X- 2X

    b) 8X – 5N ---> 1X- 7N- 6N- 7X- 3N- 2X

    c) 6X – 4N ---> 5X- 2N- 1X- 7N- 3N- 2X


    a) 3X – 8N ---> 1X- 7N- 5X- 2N- 4X- 1N

    b) 6N – 7X ---> 5X- 2N- 4X- 1N- 8X- 5N

    c) 3N – 2X ---> 4X - 1N- 8X- 5N- 6X- 4N


    a) 1X – 7N ---> 8X- 5N- 6X- 4N

    b) 5X – 2N ---> 6X- 4N- 3X- 8N

    c) 4X – 1N ---> 3X- 8N- 6N- 7X

    Another option and for me, simpler to remember.

    Set exhaust when intake starts to close, set intake when exhaust starts to open.

    This is most accurate way.......your always on the base circle of the cam using this method.
