Description
Overview:
This genuine Briggs & Stratton governor spring (OEM No. 596464) is a small but critical engine control part for maintaining steady engine speed under changing loads. Built from high‐tensile spring steel and formed as an extension spring with hook ends, it links the governor mechanism to the throttle to stabilise RPM and prevent hunting or over‐revving. It is engineered for Briggs & Stratton small petrol engines commonly found on garden machinery, particularly walk‐behind lawn mowers. Designed to meet factory specifications for tension and length, it provides reliable speed regulation on the 500 Series and is also compatible with the 7205 Series and 750 Series engines. As a genuine part, it supports consistent performance, smooth running, and long service life when replacing worn or stretched springs during routine maintenance.
Key Features:
- Genuine Briggs & Stratton OEM 596464 for assured fit and function on specified engines
- High‐tensile spring steel construction with a protective finish for durability and corrosion resistance
- Accurate speed control across idle and load for smoother cutting and reduced surging
- Direct‐fit replacement with hook ends for straightforward installation on governor and throttle linkage
- Restores correct throttle response and helps prevent overspeed conditions
- Built to OEM dimensions and calibrated tension for consistent, repeatable performance
- Supports fuel efficiency, cleaner running, and reduced engine wear over time
- Suitable for routine service to replace fatigued or stretched governor springs with minimal downtime
Typical Applications:
Used on Briggs & Stratton engines fitted to walk‐behind lawn mowers, rotary mowers, scarifiers, and other compact garden machinery. Ideal when engines exhibit hunting, uneven idle, sluggish throttle response, or inconsistent top speed due to a weakened governor spring. Helps maintain stable RPM for cleaner cuts and reliable operation across varied grass conditions.
Also known as:
Governor tension spring, engine speed regulator spring, throttle governor spring, speed control spring. These names refer to the same component in the governor linkage that balances throttle position against load to keep engine speed stable during use.
