Small Engines (Lawn Mowers, etc.): B&S Carb on 20 Toro hand 5w68m Mower, throttle shaft, assembly drawings


Question
Hi, My carb is not connected to governor correctly. Runs very fast & throttle
Throttle does nothing, mower runs very fast all the time. Mower runs fine
otherwise. I pulled the carb & cleaned it thoroughly & I do not think it was
correctly connected when disassembled. (It was given to me by a very old
friend)Do you have a diagram showing how thin rod from throttle shaft
attaches to mower & where the little spring goes. Many thanks Andy

Answer
Hi Andy:

I Do Not have a Picture or a Diagram, but this May Help. **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 the Other End of this Spring Attaches 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.**  If you Removed the Governor Arm to Remove the Carburetor, then Reset the Governor. **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 the Mower at this Site Addy, https://lookup3.toro.com/partdex/default.cfm and Select Start Parts Viewer. Now Enter the Model Numbers. Now Select View Assembly Drawings. **If you Need Assistance in Locating the Model Numbers, then You can Go to this Site Addy; https://lookup3.toro.com/partdex/default.cfm and Select Step 1.**  If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
