Should Choke be open or closed when starting?

The choke is only used when starting a cold engine. When doing a cold start, the choke should be closed to limit the amount of air going in. This increases the amount of fuel in the cylinder and helps to keep the engine running, while it is trying to warm up.

How does a carb choke work?

By restricting the flow of air into the throat of the carburetor, the choke valve reduces the pressure inside the throat, which causes a proportionally-greater amount of fuel to be pushed from the main jet into the combustion chamber during cold-running operation.
