When the engine is first started, a very rich air/fuel mixture is required because cold fuel does not turn into a gas. The choke at the top of the carburetor provides the richer mixture by closing thus creating an area of low pressure inside the throat of the carburetor which helps to pull additional fuel through the main metering circuit. At idle there isn't enough air flowing through the carb float to pull fuel through the main discharge nozzle. The manifold vacuum rather than normal venturi vacuum helps to draw the extra fuel through the main metering circuit by temporarily choking off the air supply. When the choked engine is cranked, fuel is pulled into the engine through the idle port, the transfer port and also the main metering circuit. Combined with the reduced air supply, it creates the very rich mixture that's needed to start a cold engine.As soon as the engine starts, it needs air to keep running and to offset the very rich fuel mixture. This is why the choke pull-off is important as it is attached to the choke linkage where it pulls the choke plate open slightly as soon as the engine starts. If the choke pull-off is defective because of a vacuum leak or ruptured diaphragm, the engine may be hard to start or stall. You can adjust the choke pull-off by bending the "U-shaped" pull-off linkage. Do not bend too much as, it may open the choke too far, allowing too much air which will cause the engine to stall. \ This item is shipped free using our super saver economy delivery service (2 to 11 business days) or choose or expedited service (2 to 4 business days) for only $2.49 more!
