Which position should be selected on the ENG Start Selector for a manual dry motor?

• A. Start position
• B. Motor position
• C. Run position
• D. Off position

Answer: (B)

Selecting the Motor position on the ENG Start Selector for a manual dry motor is the correct choice because this setting allows the engine's starter to engage without introducing fuel into the combustion chamber. The dry motor procedure is used primarily for clearing a flooded engine or for troubleshooting purposes without actually initiating a fuel flow or ignition sequence. By placing the selector in the Motor position, the starter can turn the engine over, which is essential for achieving the necessary engine operation conditions or performing diagnostic checks. This position ensures that the engine is cranked safely, allowing for systems checks while preventing any risk of engine damage that could occur from premature fuel introduction or combustion efforts.
