    Assuming the AF ratio of all the air passing through the engine is 12:1 or so over the full rpm range then this graph shows a neat correlation of the trapping efficiency and torque curve. Very interesting.

    The sensor is measuring excess oxygen, not mixture, maybe its not so much the jetting being wrong as the airflow being wrong
    My neighbours diary says I have boundary issues

    Yes excess oxygen in the AF that was not trapped and burnt.

    Are you looking for standard RG50 reads? Could find you some if it would help.

    The round cast head looks like a Chris Ziffle creation.
