Small Engines (Lawn Mowers, etc.): Briggs 17 hp engine, briggs and stratton, throttle shaft


Question
I have a 17hp Briggs and Stratton engine model 407777 type 0128E1 code 000627YG. It was running wide open. I suspected a governor problem and took it to a local repair shop. They took it apart and the governor gear seized to the shaft and wallowed the mount hole in the block. I bored and sleeved the block and reassembled with all new parts but I am not sure how the springs attach and not sure exactly how to set the governor. I cannot locate a diagram for the spring and linkage configuration. Any information would be helpful. Thanks.

Answer
Hello Bob:

1- **The Throttle Cable Attaches to the Throttle Control Bracket. The Cable Moves a Slide that Moves a Pivot. The Pivot has the Spring  Attached to it and to the Governor Arm. The Solid Link Connects to the Governor Arm and goes to the Throttle Shaft on the Carburetor.  When the Throttle Cable is Moved it Moves the Pivot and the Pivot Pulls the Spring. The Spring Pulls the Governor Arm and the Governor Arm Moves the Throttle Shaft. Usually the Spring is in the Lower Hole in the Governor Arm and the Solid Link is in the Top Hole of the Governor Arm.** 2- To Reset the Governor; Loosen the Governor Arm Bolt and Turn the Governor Shaft Clockwise Until it Stops. Using the Governor Arm Hold the Carburetor to Full Throttle. Now with the Shaft Full Clockwise and the Governor Arm and Carburetor Held at Full Throttle, Tighten the Governor Arm Bolt. If the Engine Still Runs Full Throttle, then Reverse the Rotation of the Governor Shaft, but Still Hold the Carburetor at Full Throttle with the Governor Arm. If it Still Runs at Full Throttle, then Check the Internal Governor. You can View a Breakdown/IPL of this Engine at this Site Addy, http://www.smallenginepartswarehouse.com/parts.asp and Select the Shop Online Parts Look Up. Then Select the Model Tab. Then Select the OEM and Enter the Model and Type Numbers. Then Double Click on the Model in the Results Area. Now you can Select the Section of the Engine you Wish to View. Hope this Helps.

Good Luck
