Might try cupping aluminum prop.  I have had very good lock cupping to accomplish 2 things at once.  Reduce rpm’s to low end of max (4400) while increasing acceleration.  Good Prop shop can cup stainless, as well.  Rebuild 2 barrel carb wouldn’t cost much and very well may solve problem.  Good luck.
