🔍 Key Concepts

• Centrifugal governor action when engine load suddenly decreases (what happens to speed and flyweights?) • How movement of the ballhead and speeder rod is transmitted to the floating lever in MO-0092 • Which end of the floating lever is connected to the actuating compensation piston and which to the speeder rod

💭 Think About

• First, imagine the engine load drops. Does the engine try to speed up or slow down, and how do the flyweights react? • As the flyweights move, does the ballhead move up or down, and what does that do to the speeder spring and speeder rod? • Given that motion of the speeder rod, which direction must the speeder-rod end of the floating lever move for the pilot valve plunger to begin correcting fuel flow?

✅ Before You Answer

• Verify from the illustration which pivot is the fulcrum for the floating lever and which end is free to move up or down. • Trace the mechanical linkage: flyweights → ballhead → speeder spring → speeder rod → floating lever. Make sure the direction of each motion is consistent. • Check that your chosen motion would cause the power piston to move so as to reduce fuel after a load decrease (i.e., counter the speed increase).
