Fuel on, fuel pump on, mixture rich, mags on, throttle set (half open, though may vary for type), crank starter. Curses, I have forgotten where the carby heat should be, as I have more or less stopped flying carby heat aeroplanes just lately. I think it should be hot but am not sure (edit: SC, who is an instructor, makes clear that carby heat should be on, see below ).
If you have lots of height to play with, you can in theory try diving to a high speed (depending on type) and then rolling in the direction opposite to the prop rotation whilst cranking the starter with the throttle half open. This is recommended for the type I mainly fly which has an injected I0360 Lycoming (dive to 150 knots, expect to lose 1000 feet, it says). Haven't tried it myself.
