          HOT ENGINE START<\/h3>\n\n\n\n

          When:<\/strong> Engine has been used recently<\/p>\n\n\n\n

          Procedure:<\/strong><\/p>\n\n\n\n

            \n
          1. DO NOT turn on fuel pump<\/strong> (will flood engine)<\/li>\n\n\n\n

            When:<\/strong> Engine has been flooded (e.g., fuel pump left on)<\/p>\n\n\n\n

            Procedure:<\/strong><\/p>\n\n\n\n

              \n
            1. Mixture to LEAN<\/li>\n\n\n\n
            2. Power lever FULL<\/li>\n\n\n\n

              2. Oil pressure must never<\/em> drop below the green range.
                If it does, immediately reduce RPM until pressure returns to green.<\/li>\n\n\n\n
              3. Taxi at low RPM (up to approx. 1500 RPM) as soon as the engine runs smoothly.
                Elevated oil temperature is not required for taxi.<\/li>\n\n\n\n
              4. Run-up may be performed when:
                a) oil temperature has begun to rise, and
                b) the engine responds normally when increasing power to 2000 RPM (no roughness or hesitation).<\/li>\n\n\n\n
              5. Do not take off until the oil temperature has entered the green arc (160 \u00b0F).<\/li>\n<\/ol>\n\n\n\n
