Narrative:
On start; #2 engine started normally; then rolled back and shut down. Subsequent start was successful. Taxi was normal. Just after brake release; #2 engine rolled back and operated erratically. Aborted takeoff at approximately 25 KTS. Returned to gate and gave airplane to maintenance. Supplemental information from acn 653043: at starter cut-out at 46% N2; the engine rolled back and fuel flow indicated zero. As I reached for the start lever; it became apparent that it was not all the way up and in the idle detent. We aborted the start at that time; motored the engine to ensure no fuel vapor accumulation and attempted another start. Callback conversation with reporter can 653042 revealed the following information: the story reporter got was the engine main fuel control was replaced. This is secondhand information from the technicians at the station where the event happened.

Narrative: ON START; #2 ENG STARTED NORMALLY; THEN ROLLED BACK AND SHUT DOWN. SUBSEQUENT START WAS SUCCESSFUL. TAXI WAS NORMAL. JUST AFTER BRAKE RELEASE; #2 ENG ROLLED BACK AND OPERATED ERRATICALLY.

AS I REACHED FOR THE START LEVER; IT BECAME APPARENT THAT IT WAS NOT ALL THE WAY UP AND IN THE IDLE DETENT. WE ABORTED THE START AT THAT TIME; MOTORED THE ENG TO ENSURE NO FUEL VAPOR ACCUMULATION AND ATTEMPTED ANOTHER START. CALLBACK CONVERSATION WITH RPTR CAN 653042 REVEALED THE FOLLOWING INFO: THE STORY RPTR GOT WAS THE ENG MAIN FUEL CTL WAS REPLACED.
