We would say that the “choke” is on or closed. This restriction of air flow reduces the amount of air available for combustion which means that the air fuel mixture is very rich. … The “choke” is off when the choke lever is down or when the choke lever is facing you if your choke is a handle bar mount.

Does choke open or closed carburetor?

Runs Better With Choke
