Small Engines (Lawn Mowers, etc.): Tecumseh Auger, spray lubricant, war between one

Question
Hi, I have an auger with a Tecumseh engine, model number tmo49x.  When I start the auger it runs at full throttle even when I am not giving it any throttle.  The engine often runs considerably faster than "full throttle" which I know can harm the engine.  I took the gas tank off to look at the carb, but do not see anything wrong other than the valve will not close inless I force it to with a screwdriver.  I feel like there may be a spring missing that pulls it back closed.  Thanks for the help.

Hello Brian:

>>Spray the Carburetor and Associated Linkage with PB Rust Catalyst or any Spray Lubricant.
>>From your Description of the Carburetor Valve it Sounds like everything is Frozen and Simply Requires Lubrication.
>>Make Sure the Linkage is Not Binding.
>>This Linkage should move Freely and the Carburetor Control Valve should Rest in the Full Throttle Position when the Engine is Not Running.

Fill Out the OEM Part Diagrams Look Up by Model Fit. Select Carburetors. Now Select the Carburetor # (example: 632370A).
>>The Governor System behaves like an Unending Tug of War between One of Two Governor Springs, which Pull the Throttle Toward the Open Position, and a Spinning Crankshaft, which Tries to Close the Throttle. When the Load on the Engine Increases - a Typical Example is when you Move your Running Lawn Mower from the Driveway to the Grass - Crankshaft Revolutions Drop. But the Governor Spring is Still Tugging, Causing the Throttle Plate to Open. In Response, a Larger Volume of Air-Fuel Mixture Enters the Carburetor, Increasing Engine Speed to Compensate for the Increased Load. The Crankshaft Speeds Up, and the Tug of War Resumes, until a New Equilibrium is Achieved. With Each Change in Load, the Tension Between the Governor Spring and the Load Brings about a New Equilibrium, known as the Engine's Governed Speed. Neither Side Wins until the Engine is Shut Off. At that Point, without the Crankshaft Spinning, the Governor Spring Pulls the Throttle to the Wide-Open Position. Two Types of Governors are Common on Small Engines - Mechanical and Pneumatic.
