Two pilot instructors carred out a control flight following the change of the propeller regulators on the two engines. After the voluntary engine stop and the restart of the engine n°1, the pilot increased the power to 70% towards a speed of 130kt. The plane suddenly yawed. Engine n°1 emitted strong vibrations. The pilot made a voluntary stop of this engine. Then he performed the "engine failure" checklist. He involuntarily cuts the fuel supply of engine n°2 by passing the lever on Cut-off instead of Crossfeed. After 20 seconds, engine n°2 misfired. The pilot realized his mistake and switched the fuel lever back to Crossfeed. He returned to the departure airfield and landed without further problems.
