Was the same "very flat acceleration and really no spunk above 1/2 throttle" happening before the new Dyna-S was installed?
What, if any, difference in engine performance resulted from installing the new Dyna-S?
Was any other engine work done besides the Dyna-S?
Did the "very flat acceleration and really no spunk above 1/2 throttle" occur spontaneously, or gradually worsen over some period of time?
Is there any doubt about whether the correct mark was used when timing the new Dyna-S ignition?
As known, the F mark -- not the T mark -- should align with the case mark at idle rpm.
Good Fortune!

If you are far off, enough that a plug chop shows anything, the symptoms will be obvious right away anyway. (Black smoke, bogging if too rich, or very weak running with popping and running hot if too lean.)

Imo, the brief stumble as described is not attributable to the main jet size, and not attributable to minimally imperfect ignition timing.
Perhaps the pilot circuits are not yet perfectly clean.
If the carbs at hand are pilot mixture version instead of pilot air version, can modify the above described cleaning method accordingly.
The idea it to assure that the mixture passes without obstruction into the carb bore.
If not already done, would perform the clear tube test to assure that all carb fuel levels are within specs.
And also assure that the choke plungers are all fully down and closed when the choke is supposedly OFF.
