    Timing 4 degrees BTDC, 650 rpm. Use number 8 cylinder for timing, not number 1.

    Adjust timing, then idle down.
    Adjust timing, then set mixture.

    Just keep tweeking it. Keep the vac advance line blocked off so that it can't suck air. If the carb is properly adjusted, there will be no vacuum at idle, assuming the power valve is not blown.

    With MSD, your plug gap should be about .050-.055 for best spark.
