Hesitates When Accelerating (Hot)

Definition: Momentary lack of response as the accelerator is pushed down. Can occur at any vehicle speed. Usually most severe when first trying to make the vehicle move, as from a stop sign. May cause the vehicle to stall if severe enough.
POSSIBLE CAUSE ACTION
Faulty ignition/restricted exhaust Check exhaust system for restrictions, check ignition timing, vacuum advance for correct settings, refer to IGNITION SYSTEMS

Accelerator pump Check for dirt in accelerator pump circuit, mis-aimed pump jets, inoperative pump, misadjusted pump linkage, clean, adjust as necessary, refer to ADJUSTMENT PROCEDURES

Inoperative secondaries Check for sticking secondary throttle valves/air valves, lubricate as necessary, refer to MAINTENANCE PROCEDURES
