Wrongo, professor.  More mass means more constant engine speed, which is
only noticeable at low rpms, but means less bumpiness in the idle  (i.e.
less of a back massage from your 'rocco).
True that other problems need a good nippin' tho.

True.  True.  xspecially the butt part.

True again, and thoroughly corrected by now.

This and idle are what I'm worried about.  I also just realized that that is
why I stalled Ron's car like three times trying to get out of Duan's yard at
Cincy last year.  That and different clutch adjustment,  and, uh, some other
excuses, too.

Uh, does that mean the 3rd is stock, or feels like stock?  If it ain't
stock, what's it got, and why didn't it change?

Yes, sir, I think I will.  I guess I'm heading back to my previous plan of
light flywheel and moderate cams.  Hmmm.  Variable back pressure would solve
all of this.
