Low Engine RPM after Propellor Overhaul

I did notice on the lower left side of the AMM page uploaded, It states max rpm is 2700, and the static rpm may be 50 rpm less, that confirms the same info my hartzell book says. You stated in a shallow dive it is limiting to 2680. It sounds like in flight the governor is doing its job. Is the adjusting screw backed out or have you just verified that the control arm is touching the limit screw?

The control arm is touching the limit screw, so that is good...

The prop should make 2650 static according to the manual.  See the note at the bottom of the page.

Clarence,

What do you think about this remedy? If I have one more turn on the stop to get the strobe tach to reach 2700, should I adjust the stop there and go with a static 26XX  during run-up and 2650 in climb-out with the analog rpm gauge; knowing the true rpm is 2700? Or adjust the control arm one turn clockwise and adjust the stop accordingly to get the airplane's gauge to read somewhat correctly?

You certainly could do that to gain the adjustment you need. Although 20 RPM is not a big difference in horsepower.
