On final approach when throttles were advanced, he discovered the right eng was not running and the left eng would not respond normally. He elected to land immediately and put the acft down on level terrain. Post accident exam of the right eng disclosed evidence of having been operated with an excessively rich mixture. Density alt at the time of the accident was calculated to be 9,819 ft MSL.
