Accelerator Pump Adjustment
The pump adjustment should not be changed from the
original factory assembly adjustment unless measure
ment indicates it is not within the specification. The
pump lever is hardened steel and bending it is very
difficult. Do not attempt to bend unless absolutely
necessary.
(1) With throttle valves completely closed and fast
idle adjustment screw off fast idle cam step, measure
distance from air horn casting to top of pump stem.
Refer to Specifications.
(2) If adjustment is necessary, remove pump lever
retaining screw and lever by rotating from pump rod.
CAUTION: Do not bend lever sideways or twist it.
(3) Place lever in soft jawed vise and bend end of
lever as necessary to obtain correct dimension.
(4) Install pump lever and retaining screw.
(5) Check adjustment and if correct tighten retain
ing screw securely.
(6) Open and close throttle valves to test linkage for
freedom of movement and lever for correct alignment.
