QuestionI just bought this mower and when you start it up, it only runs at full throttle. I cannot locate an owners manual anywhere so I am at a loss as to what to do. Any suggestions as to where to locate a manual, or how to solve this problem would be greatly appreciated. Thank you.
AnswerHello Eric:
>>Locate the Carburetor.
>>Follow the Solid Linkage from the Carburetor to the Governor Arm.
>>Start the Engine.
>>Can you Move the Governor Arm by hand and Regulate the Engine Speed back to Idle?
>>If Yes, then Check the Throttle Control Cable and make Sure it is Moving the Throttle Control Bracket.
>>If the Throttle Cable is Moving the Throttle Control Bracket, then Try Setting the Governor.
>>If the Throttle Control Bracket is Not Moving when the Throttle Cable is Moved, then Check for a Broken Throttle Cable.
>>The Following is an Instruction File I Made for Setting the Governor Arm Correctly. Any Input is Appreciated.
>>If you Removed/Loosened the Governor Arm from the Governor Shaft or Put the Linkage in a Bind when the Carburetor was Removed, 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.**
>>If No, then Remove the Carburetor from the Engine and Check the Throttle Control Valve/Flap in the Throat of the Carburetor.
>>Sometimes the Throttle Control Valve/Flap will come Free and Lodge in the Intake or even go through the Engine and Into the Muffler.
