Huh???
Don't understand this.  Prop balancing is done completely independent of
the engine.  At least it has always been done that way where I come from. 
Have I been missing something?  

I recommend a complete overhaul of the prop to bring it back up to factory
specs before engine run-in.  This assures any adverse vibrations will be
coming from the engine during run-in.  Besides, the prop is probably
almost
as old as the plane and to put an old unbalanced prop on a new engine
doesn't seem the wise thing to do.
