Abstract
A vacuum-operated choke system for use with an internal combustion engine and method of using the same including a vacuum actuator for moving an actuating arm for connection to a choke valve of an internal combustion engine from a first position to a second position, an air valve in communication with the vacuum actuator, and a vacuum mechanism in communication with the vacuum actuator and the air valve for causing air to discharge through the air valve whereby the vacuum actuator can move the actuating arm from the first position to the second position and whereby the air valve is operable to allow air to enter the air valve whereby the vacuum actuator can move the actuating arm from the second position to the first position. The choke system can include a manifold defining at least one air inlet and one air outlet communicating with the vacuum actuator for passage of air into and out of, respectively, the vacuum actuator and can further comprise an orifice selector plate attached to the manifold, wherein the orifice selector plate can be positioned to cover all of the air inlets but one to control airflow through the manifold.
