Narrative:

We attempted a rolling takeoff. After selecting autothrottles the captain (pilot flying) noticed the throttles wouldn't advance above mid-range using either the autothrottles or by pushing on them manually. We performed a low speed abort at 60 KTS without incident. Back at the gate; the mechanic informed us that some pins that restrict throttle movement were not removed after some recent fuel control maintenance. This was a classic attention to detail mistake. The plane was late coming from the hangar where the fuel control units had been worked on. I don't know it for a fact; but I feel the mechanics might have been rushed to return the aircraft to service.

Original NASA ASRS Text

Title: Two pilots and a Mechanic report about Part Power Stops (PPS) that had not been removed from both engines on a B757-200 aircraft after a Fuel Flow Governor (FFG) had been replaced. The Part Power Stops prevented full takeoff power; requiring a Rejected Takeoff (RTO).
