What was found
DURING ENGINE START, WHEN THE START BUTTON IS PRESSED AND FFC LEVER WAS ADVANCED, NORMAL IGNITION AND ACCELERATION WOULD OCCUR UNTIL REACHING 25 TO 30% NG. AT THAT TIME ACCELERATION WOULD ALMOST STOP. THE ENGINE WOULD NOT ACCELERATE UNLESS THE T4 WAS KEPT AT THE TOP OF THE GREEN ARC. EVEN THEN ACCELERATION TO 40% WAS VERY SLOW. WHEN ENGINE WAS COLD, ACCELERATION TO 40% WOULD TAKE 45 TO 65 SEC. WHEN ENGINE WAS WARM ACCELERATION TO 40% TOOK 35 TO 40 SEC.
