4.3 STARTING PROCEDURES
4.3.1 COLD ENGINES
The following starting procedures are recommended, however, the
starting conditions may necessitate some variation from
these procedures.
1. Perform pre-flight inspection.
2. Set propeller governor control in "High RPM" position.
3. Open throttle approximately 1/4 travel.
4. Turn boost pump "ON".
5. Move mixture control to "FULL RICH" until a slight but steady
fuel flow is noted (approximately 3 to 5 seconds) and return
mixture control to "IDLE CUT-OFF".
Turn bost pump "OFF".
6. Engage starter.
7. When engine fires release the ignition switch back to "BOTH".
8. Move mixture control slowly and smoothly to "FULL RICH".
9. Check the oil pressure gauge. If minimum oil pressure is not
indicated within 30 seconds, shut off the engine and determine trouble.
4.3.2 HOT ENGINES
Because of the fact that the fuel percolates and the system must be cleared of vapor, it is
recommended to use the same procedure as outlined for cold engine start.
