I'll start leaning it out, especially on the low end. My question is what should be the target A/F for max power. I would guess the modern trend on 10 percent ethanol is leaner than the old fashion 12.5 target. Any thoughts. This as 12.0 to 12.7, grunt method works pretty well I guess.

I change the gauge to lambda today .8523 rich to .9020 lean, max power. |
I have my PE set to 1.150 (.870 lambda) at peak power.
