Briggs & Stratton 842743 Governor Spring OEM Replacement Part

The Briggs & Stratton 842743 Governor Spring is a genuine OEM replacement part designed to maintain precise engine speed regulation in Briggs & Stratton small engines. The governor spring works in conjunction with the mechanical governor assembly to balance throttle input against engine load, keeping RPMs stable during operation.

Using a genuine Briggs & Stratton part ensures an exact fit and correct spring tension — critical factors for proper governor function. Aftermarket springs with incorrect tension ratings can cause engine surging, over-revving, or poor throttle response.

Key Features:

• Genuine OEM Briggs & Stratton part — manufactured to original factory specifications
• Maintains correct spring tension for stable engine speed under varying loads
• Direct replacement for worn, stretched, or broken governor springs
• Engineered and tested to deliver optimum performance in Briggs & Stratton engines
• Helps ensure continued compliance with applicable EPA emission regulations
