Understanding Small Engine Governors

The video explains the operation of small engine governors, focusing on common misunderstandings. It details how the throttle is opened and closed, describing the roles of the governor spring and flyweights. The video also covers how forces are balanced to maintain a steady engine speed, providing a comprehensive understanding of governor mechanics.

What is a common issue even experienced technicians face with small engine governors?

• Understanding the throttle mechanism

• Misunderstanding the governor operation

• Identifying engine parts

• Adjusting the speed control lever

What component increases tension when the speed setting is set to fast?

• Crankshaft

• Governor spring

• Governor flyweights

• Throttle plate

Which part of the engine is responsible for driving the governor gear?

• Crankshaft

• Governor spring

• Speed control lever

• Throttle linkage

What happens when the governor flyweights move outward?

• The throttle opens

• The regulating pin moves towards the governor gear

• The regulating pin moves away from the governor gear

• The engine speed decreases

What are the two forces acting on the governor lever?

• Governor spring and throttle linkage

• Governor flyweights and crankshaft

• Throttle plate and speed control lever

• Governor spring and governor flyweights

How does the governor spring force change?

• By adjusting the throttle linkage

• By moving the speed control lever to fast

• By increasing engine speed

• By decreasing engine speed

What occurs when the engine speed is lost?

• Governor spring force exceeds flyweight force

• Throttle closes

• Governor flyweight force exceeds spring force

• Throttle remains unchanged

What happens when the engine over speeds?

• Governor flyweight force exceeds spring force

• Throttle opens

• Engine speed decreases

• Governor spring force exceeds flyweight force

What does adjusting the speed control lever change?

• The engine power output

• The governor spring tension

• The RPM set point

• The throttle linkage

What is achieved when the forces on the governor lever are balanced?

• Throttle closure

• Increased engine speed

• Steady engine speed

• Maximum power output
