With the C172R and S series which uses the fuel injected engines, the engine starting procedure is basically:
- prime (aux fuel pump on, mixture rich until fuel pressure stable 3 to 5 secs, mixture cutoff, aux fuel pump off)
- mixture cutoff position
- ignition start
- mixture full rich once engine starts
However, in the emergency procedures per POH, for in flight restart due to engine failure, the steps are basically:
- aux fuel pump on
- mixture full rich
So my question is, how is it for normal start, mixture is in cutoff position but in-flight restart it's in full rich?
