I am afraid that I do no understand your insinuation.

Without carb heat, I can lean back to between 65% and 75% power, depending on the day and how long the engine has been running. With carb heat on in cruise, I can pull it back much farther, probably right to cutoff if I were so inclined. The nice thing is that I have my Piper POH for backup: For Best Economy cruise, a simplified leaning procedure which consistently allows accurate achievement of best engine efficiency has been developed. Best Economy Cruise performance is obtained with the throttle fully open. To obtain a desired cruise power setting, set the throttle and mixture control full forward, taking care not to exceed the engine speed limitation, then begin leaning the mixture. The RPM will increase slightly but will then begin to decrease. Continue leaning until the desired cruise engine RPM is reached. This will provide best fuel economy and maximum miles per gallon for a given power setting. It's easy to do this with a fixed-pitch prop, since the tach gives a direct indication of power setting at any given density altitude.
