Plane in hangar, this morning, 1.5-hrs with heater on, oil was up to over 75-deg F and engine started instantly, mag check typical drop, all normal. Take off 5100 or so RPM and 960 FPM climb. Leveled off at 9,000 MSL and 5,000 RPM then noted fuel flow of only 3.3-GPH. Typical is 4.0 or 4.1 but everything was working normally and increasing RPM increased fuel flow reading. Indication is on a Dynon D-180. On landing I stopped on taxi way and left engine idle at 2100 or so and fuel flow showed 0.0 GPH My "guess" is that the cold soak the previous night somehow effected the impeller in the fuel flow module and more or less slowed it down ... gas was also cold. Your take?
