Understanding the Role of the Briggs and Stratton Governor Spring
Before diving into the installation process, it's important to grasp what the governor spring does and why it's critical for your engine's operation.
What Is a Governor Spring?
The governor spring is a component of the engine's governor system, which regulates engine speed by adjusting throttle movement. It works in conjunction with the governor arm and linkage to maintain a consistent RPM, regardless of load variations.
Why Is the Governor Spring Important?
- Maintains stable engine speed
- Prevents engine over-revving
- Ensures smooth power delivery
- Protects engine components from excessive stress
A faulty or worn governor spring can cause inconsistent engine performance, surging, or even damage to internal parts. Replacing or installing a new spring correctly ensures your engine runs reliably and efficiently.
