yes you should slightly increase the max throttle stop. be careful doing so as too much can cause the governor to bind up. also be sure to check the linkage is moving to the new limit.

Is there anything I'm aiming for in particular? Or is it an arbitrary number of turns?

try .5 to 1 at first and maybe 2-3 max be prepared to block the intake in case it sticks the governor. it shouldn't need much to make it use the extra rack travel.
