My new M20F flies well and appears to be putting out full rated power. But I have yet to see an honest 2700 RPM on the tach. 2625 is the most I can get in cruise, even at low altitude. It's a digital tach so I doubt this is an issue with tach error.
I don't intend to do a lot of cruising at 2700, so it's not a big deal, but I'd still like to know why I can't get that last 75 RPM. Any thoughts? Maybe a cable or prop governor adjustment?
