Ignition timing

Discussion in 'General Amphicar Discussion' started by DAVIS,BRIAN R, Sep 17, 2000.


    After straining my back, I finally found that damn timing mark on my crank
    pulley! It's a 1/16" hole drilled through the pulley right at the edge. This
    is top dead center.

    The manual says that ignition timing should be set at 15 degrees BTDC (8:1
    compression ratio), but there's no marks on the crank pulley to indicate
    that point!

    Does this mean that you just have to guess as to where that is?

    I turned the adjustment on the vacuum advance, but the timing mark didn't
    move. (Using a strobe light). Does this mean that I have to do it the 'old
    fashioned' way by loosening the distributor bolt and rotating it?

    Thank you!
