===Choke=== Under cold conditions, a choke circuit can be used which increases the amount of fuel in the intake charge. This is a solution to the problem that gasoline does not atomize well when it is cold. This circuit is activated either manually or by a bimetal coil (aka "automatic choke"). The bimetal coil can be heated by the engine or by a small electrical heating element to release the choke as the engine warms up. Most chokes also have a fast idle feature to them to allow the engine to remain running without the operator having to use the throttle during warm up. Again, the reason for every circuit that a carburetor has is to provide a suitable air/fuel ratio and amount of air/fuel for operational/environmental conditions.
