Flying the A-20G, start both engines at the same time and go flying... Later, when I landed, I shut off the engines one at a time. Upon restart, the aircraft would not taxi straight, but in a circle, as if one engine was not running. Rudder and brakes do not overcome the tendency to turn.
So, I played around and found that whatever engine was shut down first, upon restart, the plane taxied as if the engine was still shut down. I could get this effect in either direction depending upon which engine I shut down first.
To fix the problem, you must restart both engines at the same time.
