Narrative:

We were performing training on the number 1 engine; how to lock-out reversers; how to open the fan cowls and c-duct. Also various components were pointed out on the engine. We were also shown where the part power stop (pps) was and had to use it; also where you would do an adjustment; to adjust engine power. Once the pps was set; it was not put [back] to its normal position. Contributing factors could have been very cold temperatures and windy outside. It was also dark. Also we are in peak season and had to keep our eyes on the time; we needed to pre-check three aircraft for later departures. All these conditions could have accelerated our training and caused the pps to be missed.problem was discovered during takeoff; pilot rejected takeoff and returned to the gate. After being told the problem we realized what happened and re-positioned the pps to its normal position and performed the rejected takeoff (rejected takeoff) inspection. Aircraft departed one hour five minutes late.

Title: A Maintenance Instructor and a Mechanic report about a Part Power Stop (PPS) that was not re-positioned to the 'stowed' position on a RB-211-535 engine prior to departure. On takeoff roll; pilots realized the number 1 engine on the B757-200 would not make takeoff power and aborted by initiating the Rejected Take-off System (RTO).
