Hi Chris,
Flightgear will already visualize external data, I've done it, just not that
often or recently and I can't remember the steps. Have a look at

I took a quick look through the FGData Aircraft directory today and came up

either the old aeromatic default values for idle manifold pressure (minmp)

The engine needs to reach 440 RPM to start (80% of 550, the coded idle RPM) if
you're reaching above 440 RPM make sure you've engaged fuel and magneto
