I like to run LOP all of the time. Here is what I do when I am stuck down low. Looking for feedback. O-360-A1A, 100LL, FP
Below 3,000 feet I will fly at 2,400rpm and lean to about 20LOP. At this point my RPM's have dropped to about 2,100rpm. Then I go to Wide open throttle, which causes roughness. I then enrich until the engine is reasonably smooth and back at 2,400rpm. I do it this way because I don't want to lean through the peak at WOT down low, but this way I am not 100% sure that I am actually LOP. At a given lean setting, does the A/F ratio stay relatively steady through different throttle settings? My Fuel flow is about 8.4, which is 70% power IF I am LOP. CHT's are all 350 and below.
