linkage briggs and stratton throttle spring diagram

If you’re working on a Briggs and Stratton engine and need to adjust or replace the throttle spring linkage, it can be helpful to have a diagram to guide you. In this blog post, we’ll provide a Briggs and Stratton throttle spring diagram and explain how to adjust or replace the linkage as needed.

Throttle Spring Linkage Diagram

The following diagram shows the throttle spring linkage for a Briggs and Stratton engine:

As you can see in the diagram, the throttle spring is connected to the carburetor and the governor’s arm. The governor’s arm is connected to the throttle control lever, which is what the operator uses to control the engine speed.

Adjusting the Throttle Spring Linkage

If your engine is running too fast or too slow, you may need to adjust the throttle spring linkage. Here’s how to do it:

  1. First, make sure the engine is turned off and the spark plug wire is disconnected.
  2. Loosen the screw on the governor arm that connects it to the throttle control lever.
  3. Move the throttle control lever to the desired position (either faster or slower).
  4. Hold the throttle control lever in place and move the governor arm in the same direction until the spring is taut.
  5. Tighten the screw on the governor’s arm to secure it in place.
  6. Reconnect the spark plug wire and start the engine to check the speed.

Replacing the Throttle Spring Linkage

If the throttle spring or linkage is damaged or broken, you’ll need to replace it. Here’s how:

  1. First, remove the air filter and air cleaner housing to access the carburetor.
  2. Remove the old throttle spring and linkage by disconnecting it from the carburetor and governor’s arm.
  3. Install the new throttle spring and linkage, connecting it to the carburetor and governor’s arm as shown in the diagram.
  4. Reinstall the air cleaner housing and air filter.
  5. Start the engine and check the throttle operation.


The throttle spring linkage is an important component of a Briggs and Stratton engine, as it controls the engine speed and performance. With the help of the diagram and these instructions, you can adjust or replace the throttle spring linkage as needed to keep your engine running smoothly. Remember to always turn off the engine and disconnect the spark plug wire before making any adjustments or repairs to your engine.
