Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Accelerating Pump Rod Adjustment
Back out slow idle speed (and fast idle speed) screws until throttle valves are completely closed. Make sure pump rod is connected in proper hole of arm as indicated in specification table. Hold throttle valves in closed position and use a gauge or scale to check pump adjustment.
If a scale is used, measure distance from top of air horn casting to bottom of pump plunger shaft (see Specifications ). If height not correct, adjust by bending pump rod.
