A770
Anyone no what the a770 should b at idle? Is 1300 rpm right? The a300 is around 1090-1120. That's a big difference. And way easier to handle as operator.

1300 RPM is right in middle of specification. Engine in 770 is same engine that was used in S330. Timing and fuel delivery are different than the 300 to gain extra HP. EPA has an emission standard for low RPM (idle) as well as @ full power, so I think this is why the idle speed is higher. S330 had same idle RPM spec.
