  20. Just as a side note, using the sensor showed how *very* lean the emissions
  21. certified Holley 650 is calibrated from the box. At cruize the carb was
  22. delivering a miezerly 20:1 A/F.  During hard accelleration the ratio would
  23. only climb to about 14.0:1.  I jetted up 2 steps primary & secondary and it
  24. now delivers about 18:1 cruise and 12:1 at WOT.  What a difference!  The
  25. engine *really* comes alive with the additional fuel. Yikes!
