Throttle Kicker Check

1. Hold the throttle half way open to allow the plunger to extend fully.
2. Apply 20 inches Hg (68 kPa) vacuum to the throttle kicker.
3. Apply finger pressure to the plunger to see if it is fully extended. If not, replace the throttle kicker.
4. Observe the vacuum gauge. The vacuum should hold for at least 20 seconds. If not, replace the throttle kicker.
5. Release the vacuum to the throttle kicker.
6. Apply finger pressure to the plunger to see if it has returned to its retracted position. If not, replace the throttle kicker.
