Full choke (when engine is completely cold)
Half choke (used when the engine has started from cold, but is not yet warm enough for no choke at all- should be an immediate progression from the full choke setting once the engine has started)
Run position (no choke at all- for when the engine has warmed-up and is the setting for normal operation of the mower)
