Briggs & Stratton Governor Spring - 690254

Product Details & Features

Ensure your Briggs & Stratton engine maintains stable and controlled speed under varying load conditions with this genuine governor spring (Part 690254). A critical component of the throttle-governor system on many Briggs & Stratton Sprint, Classic and Quattro air vane governed engines, this spring provides the correct tension needed for reliable governor operation. 

The governor spring applies tension between the governor linkage and throttle control to help regulate engine RPM (revolutions per minute). As engine load changes — for example when the cutting blades engage or terrain varies — the governor and its spring work together to maintain consistent speed, prevent over-revving and keep performance smooth and efficient. This particular spring is colour-coded blue and calibrated for approximately 2800 RPM applications. 

Key Features:

• Genuine Briggs & Stratton OEM Part: Engineered to meet original equipment specifications for a precise fit and dependable service. 

• Correct Tension & Calibration: Designed to provide the proper spring rate for stable governed speed on applicable lawn mower engines. 

• Direct Replacement: Replaces older part numbers such as 263116 and 691860, ensuring compatibility with many Sprint, Classic and Quattro series engines. 

• Durable Construction: Made from quality metal to withstand repeated throttle movement and engine vibration. 

• Easy to Install: Fits directly into the governor linkage assembly with basic hand tools — ideal for routine maintenance or repair.

Why It Matters:
A healthy governor spring is essential for smooth, predictable engine performance. A worn, stretched or broken spring can cause erratic throttle response, speed surging or difficulty maintaining power under load. Replacing it with this genuine 690254 governor spring restores correct throttle control and helps your engine stay responsive and reliable during cutting, towing or other demanding tasks.
