First start (assuming it's a new or freshly overhauled engine) should be brief enough that you don't have much time to spare beyond checking basic operating parameters and shutting down. If it's a break-in engine, you don't want it to get warm enough to glaze the cylinders without having high manifold pressure (i.e. - in flight). You're looking for obvious function checks like acceptable idle RPM, good oil pressure, no smoke/fire, relatively smooth, etc.
