Aircraft
During the takeoff roll; under 50 KIAS; the left engine failed to produce power. The left engine manifold pressure only reached between 20-25 inches and the RPM reached 2000-2200. This caused the airplane to yaw to the left. The takeoff was aborted and we returned to the gate. End of incident. Left engine failed to produce power for takeoff.
C402 Captain reported rejected takeoff due to inadequate engine power.
