Briggs & Stratton 596391 Governor Spring

The Briggs & Stratton 596391 is a genuine OEM governor spring designed for small engines. This precision-engineered spring is a critical component of the governor system, which regulates engine speed by controlling the throttle position based on load conditions.

Key Features:

• Genuine Briggs & Stratton OEM part for guaranteed fit and performance
• Precision-wound spring maintains consistent tension for accurate speed regulation
• Durable construction designed to withstand engine heat and vibration
• Direct replacement part for easy installation
• Essential component for maintaining proper engine governor operation

The governor spring works in conjunction with the governor arm and throttle linkage to maintain steady engine speed under varying loads. When the engine speed increases, the governor mechanism pulls against the spring tension to close the throttle; when speed decreases, the spring helps open the throttle to increase power. Replacing a worn or damaged governor spring is essential for maintaining smooth, consistent engine performance and preventing overspeeding conditions.
