Narrative:

On initial takeoff roll, #1 engine would not reach full rated takeoff thrust. Takeoff was rejected early, IAS less than 60 KTS. Taxied back to end of runway 23 with engine anti-ice on. In position on runway 23, engines were run to 80% power and engine and engine anti-ice indications were normal. Normal full-power takeoff accomplished. All engine operation and indications were normal. Aircraft handbook does not call for engine anti-ice unless visibility is restricted by visible moisture. Defined as visibility 1 mi or less. Supplemental information from acn 299429: we both thought ice might be in engine pressure probe. We applied engine anti-ice for about 2 mins and then found left engine produced good power.

Title: TKOF ABORTED.

Narrative: ON INITIAL TKOF ROLL, #1 ENG WOULD NOT REACH FULL RATED TKOF THRUST. TKOF WAS REJECTED EARLY, IAS LESS THAN 60 KTS. TAXIED BACK TO END OF RWY 23 WITH ENG ANTI-ICE ON. IN POS ON RWY 23, ENGS WERE RUN TO 80% PWR AND ENG AND ENG ANTI-ICE INDICATIONS WERE NORMAL. NORMAL FULL-PWR TKOF ACCOMPLISHED. ALL ENG OP AND INDICATIONS WERE NORMAL. ACFT HANDBOOK DOES NOT CALL FOR ENG ANTI-ICE UNLESS VISIBILITY IS RESTRICTED BY VISIBLE MOISTURE. DEFINED AS VISIBILITY 1 MI OR LESS. SUPPLEMENTAL INFO FROM ACN 299429: WE BOTH THOUGHT ICE MIGHT BE IN ENG PRESSURE PROBE. WE APPLIED ENG ANTI-ICE FOR ABOUT 2 MINS AND THEN FOUND L ENG PRODUCED GOOD PWR.
