The throttle kicker solenoid valve, Fig. 8, throttle position sensor and throttle solenoid positioner, Figs. 9 and 10, are used when additional throttle opening is required.
The throttle kicker solenoid valve is normally closed and is made up of two vacuum ports with an atmospheric vent. The outlet port is opened to atmospheric vent and closed to the inlet port when de-energize. When energized, the outlet port is opened to the inlet port and closed to the atmospheric vent. The ports should flow air when the solenoid is energized.
The throttle position sensor supplies a signal to the Electronic Control Assembly (ECA) proportional to opening angle of carburetor throttle plate.
The throttle solenoid positioner acts as a variable carburetor throttle stop by extending its plunger when voltage is applied to the solenoid and by retracting when power is turned off. When the throttle solenoid positioner is energized it will hold the throttle at an idle position, as soon as it is de-energize the throttle solenoid positioner will act as an anti-dieseling device by automatically retracting its plunger, fully closing the throttle.
