>  from optimum of 14.7.

Actually, 14.7 is "optimum" only to a chemist or a catalytic converter.  It
provides neither best power nor best fuel economy, which I assume are the
only things TRactor motor owners are interested in tuning for.

That said, I tried mounting one on my 59 TR3A just for curiosity sake.  It
was fun to play with, but relatively useless for tuning, IMO.
