Small Engines (Lawn Mowers, etc.): HM100, war between one, spring tension

Question
I have an HM100  Tecumseh 10hp engine.
The carburetor and intake were removed and I have them.
 The linkage for the throttle cable is on the engine.
None of the governor linkage is there nor the link to the carb are here.
It has spark.

Can the engine be run without these ? What do I do?
Can I measure something so I can bend my own? What do I do?
Can I order these and just put them on?

I would prefer the safety of a governor , but it is not going to be used on a stationary run speed application.
The stuff was taken off to try and use a motorcycle carb for looks and maybe smoother off idle responce.
The engine has never started with that carb on it.
I took out the box of parts removed and found no linkages in the box. It has gone through two moves and a divorce since being removed.

Would having tried to start the engine with this carb caused a change in the governor that is keeping the engine from running?
I was told that these governors  { it appears to be inside the block}  have to be reset inside when you try and run with out the stock linkage to it and the carburetor.
Help please It powers my `42 Saftycycle and I`d like to ride her.

Answer
Hello Roger:

>>I am Sure you want to get the Best Service you can for as Little as Possible out of this Engine.
>>I Suggest you Purchase the Correct Parts.
>>The Only Component you are Not going to be Using when it is on the Go-Cart is the Throttle Bracket.
>>You should have a Go-Cart Bracket that Allows the Throttle Cable to be Attached to the Governor Arm with a Throttle Spring. When the Accelerator is Depressed, then the Throttle Spring Pulls on the Governor Arm and the Engine Throttles Up Until the Spring Tension is Reached and the Engine is Held at the Correct RPM's by the Engines Internal Governor and the Throttle Spring. You will Require the Correct Spring for your Engine to Reach Maximum Engine RPM's.

>>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.

Good Luck
