🔍 Key Concepts

• Governor hunting causes and what parts actually control speed stability • Difference between fuel control (rack settings) and mechanical linkage/freedom of movement • Effect of speed droop and why setting it to zero can be risky or inappropriate

💭 Think About

• Think about what has already been done to the governor itself (oil, flushing, compensation adjustment). What simple, external factor could still prevent smooth governor action? • Which choice deals with something that could make the governor’s motion jerky or delayed rather than changing its basic fuel setting or system design? • Ask yourself which adjustment, if done incorrectly, could create more instability instead of curing hunting.

✅ Before You Answer

• Verify which option focuses on mechanical freedom of movement rather than recalibration or redesign of the system • Check which actions are normally done last only after all simple causes (like friction or sticking parts) are eliminated • Consider which option could be dangerous or inappropriate to change on a running plant without thorough analysis (that one is less likely to be the best immediate step)
