co adjustments and o2 voltage (was high compression motors in 4kqs)

my DPR current is now between 9.6-12 fluctuating after the adjustment, i
guessed and went a tad richer.
the idle seems a little rough but i've got to go to 'lil sisters HS grad so
i'll probably monitor o2 voltages later.
it seemed to stabilize the 02 voltage closer to .6 while cruising now. i
thought a richer mixture would make a higher voltage.
go figure.
