    Right,
    there are fundamentally only two ways to reduce gas.
    1) Restrict the gas port
    2) vent the piston chamber

    This is probably the best approach. Directly fix the problem of "gas port too big".

    Venting the chamber can be done with a tiny bleed hole in the chamber itself or by making the piston more leaky.

    Notching the piston should work, as should turning down the piston diameter.

    Drilling a vent hole directly into the face of the piston should work as well.

    A .046" would probably be a good starting point.
