In summary, the "rattle point" is more dependant on idle quality than absolute rpm.   Do not be too concerned about this however.  It will cause no harm to the drive or engine.   
 
Thanks for the complete story Tracy, and John for the extra idea.  I never thought about making the idle low enough to get under the rattle point.  I had the engine running at 800 with no prop, and no problems of course.  If I could get the idle down low enough, perhaps the MAP wouldn't be duplicated in my 2-3K rpm range.  Might have to try that.  
 
Cheers,
