1) had the bore alignment checked on the wbx case -
everything is within .0005" of nominal (but we are
talking about rods?)
2)
3)
4) "little spin"... now, i'm not a strong man... not
sure how hard a little spin is :-)
5) my rods definitely seem to drop faster than that,
but i'll double check (not enough oil? who knows...)

And yes, i do have newly reconditioned rods and crank
and they do seem to measure quite consistently (at
least as consistently as i can manage).  I have been
able to procure a bonafide micrometer in the right
sizes to check the journals...

Thanks for the tips - unfortunately, in this case at
least, i am a little (lot) more comfortable with the
numbers than little spins and hard clunks.  They will
be a good reality check, though.
