I would shoot for, and do up 14.5 AFR or leaner at light part throttle cruise below 2700 RPM in high gear scope
That really helps keep the spark plugs clean scope
Anything richer than 13.8 AFR or lower at part throttle cruise seems to be more responsive but sometimes the butt dyno can be fooled by sensations work shruggy
