    I didn't invent this, but thought it worth mentioning. This is my 12 step program for living with J.A.S.

    1) Remove all spark plugs, disconnect the battery, and place transmission in neutral.

    2) Mark the #1 position on the distributor body with a light colored Sharpie or chalk.

    3) Rotate the engine clockwise with a socket wrench until the rotor is pointing at the mark, easier if you have a helper to watch this while you turn the crank. The distributor rotor will turn counter clockwise. When the rotor is pointed to the #1 firing position it is a few degrees BTDC but both valves will be closed.

    4) Make a mark parallel to the ground on the passenger side of the crankshaft pulley.

    5) Adjust the valves for #1

    6) Rotate the engine 180 degrees until the mark made in step 4 is parallel to the ground on the driver side

    7) Adjust the valves for #3

    8) Rotate the engine 180 degrees until the mark is parallel to the ground on the passenger side

    9) Adjust the valves for #4

    10) Rotate the engine 180 degrees until the mark is parallel to the ground on the driver side

    11) Adjust the valves for #2

    12) Done. Replace valve and rocker covers
