I got an output on pin 4 using your changed code. I don't think you get an output on OC0A because it is using that as the phase-correct counter. Compare the image on my original post about timers:
Notice that the "A" output does not change.
And to change the Timer from 0 to 1, simply change all "0" to "1" in the Code? (an the Pins to 12,11 on Mega)?
Try it and see. Sounds about right.
