Same engine/tranny config. as previous message about shift speeds (I-6, 4 spd. auto). Engine stalls-out if I hit the accelerator too hard from a stop. Accelerates OK if I tap the accelerator pedal a few times, then press the pedal normally. Worse when cold but present during all temp. ranges, and no diffs. when in Park or in gear. Choke clearance OK, accel. pump OK (unsure of nozzle angle), fuel/air mix OK. No hesitation at speed.
