50 RPM drop on the rich side is too rich at cruise... 50
degrees rich of peak on the EGT is about right with a carb.
With fuel injection, just a little below peak or even at
peak if the cruise power is set below 70%. At low power
settings you can run at peak since the actual temperatures
will be low. If you have a calibrated EGT (TIT) follow the
limits.
