Thoughts from those who know more than me…

Timing ?
My theory is, don't mess with your timing if you're getting run-on after turning the ignition off.
Once you turn off the key, your distributor is not producing spark, so playing with the timing does nothing.
Usually too high an idle is what causes run-on.
