🔍 Key Concepts

• How the Fuel Control Lever for Emergency Running Without Governor is connected to the main Fuel Control Lever and linkages in the illustration • The purpose of the Maximum Fuel Limiting Screw and what changing it would do to engine operation and safety • How the shutdown servomotor and the governor terminal output shaft are both tied into the same fuel control linkage via the torsional spring and take‑up link

💭 Think About

• Look closely at the labels on the lower sector‑type lever: what does its name tell you about how the engine is intended to be operated if the governor fails? • When using the emergency manual fuel control, would it be safer to leave the maximum fuel stop where it is or to alter it, and why? • Does the arrangement in the sketch appear to require physically disconnecting any linkages to the governor or shutdown servomotor, or is it designed so that another lever can assume control without disassembly?

✅ Before You Answer

• Identify exactly which component in the diagram is meant for emergency running without governor and trace how its motion reaches the fuel injection pumps • Confirm how the maximum fuel limiting screw interacts with the fuel control lever and whether any option suggests altering that safety setting • Check each answer choice against the drawing and eliminate any option that conflicts with the clearly labeled functions of the levers and linkages (especially anything requiring extra disconnection not shown as part of normal emergency use)
