Briggs & Stratton 798626 Governor Spring for 550 Series Small Engines

The Briggs & Stratton 798626 Governor Spring is a genuine OEM replacement part designed for the 550 Series horizontal crankshaft small engine. This precision-tensioned spring is a critical component of the engine's governor system, working in conjunction with the governor arm to regulate throttle position and maintain stable engine speed under varying loads.

How It Works:

The governor spring applies tension against the governor arm, controlling the carburetor throttle plate. When engine load increases and RPM begins to drop, the spring pulls the throttle open to compensate. When load decreases and RPM rises, the governor system pushes back against the spring to reduce throttle. This constant balance keeps the engine running at a consistent, safe speed.

Key Features:

• Genuine Briggs & Stratton OEM part — engineered to exact factory specifications
• Designed specifically for the 550 Series horizontal crankshaft engine
• Approximately 4.1 inches (10.5 cm) overall length
• Precision spring tension for accurate governor response to engine load changes
• Prevents engine overspeed, protecting against premature wear and mechanical failure
• Direct OEM replacement — no modifications required for installation

Replacing a worn or broken governor spring restores proper speed regulation and protects the engine from over-revving. Use genuine Briggs & Stratton parts to ensure correct fit, function, and long service life in your outdoor power equipment.
