Accelerating Pump
NOTE:
If there are two holes in pump shaft lever, place pump connector rod in OUTER hole (except Buick see Note).
With the throttle stopscrew (and fast idle screw if so equipped) backed out so the throttle valves are completely closed, measure distance from top of air horn ring to top of connector rod, using a scale or combination gauge (see "Specification Table "). To adjust, bend pump connector rod.
BUICK NOTE - For pump rod adjustment, connect pump connector rod in Outer or Inner hole of pump lever as listed for each model in Specifications. For normal operation, pump rod is connected in outer hole of pump lever. Inner hole should be used to correct an acceleration hesitation in extremely cold temperatures.
