What position does the governor spring hold the throttle plate when the engine is not running?
When the engine is not running, the governor spring typically holds the throttle plate in a closed position. This ensures that no air can enter the engine, preventing any unintentional fuel delivery. The throttle plate remains closed until the engine is cranked and begins to run, at which point the governor can adjust its position based on engine speed and load requirements.

How does a speed govenor work?
A 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 governor are common on small engines - mechanical and pneumatic.
How do you remove a lawn mower's governor?
The easiest way is to just locate the throttle shaft (not the choke shaft!) and unclip any rods, links, or springs. You'll have to rig up a way to manually control the throttle plate, because the speed control adjuster (the turtle/rabbit thing) works on the governor spring, not the throttle itself. Also, defeating the governor mechanism is a great way to destroy the engine!
Governor spring missing on Briggs 6.0 eng how does it connect to the lawn mower?
spring missing on lawn mower not sure where to install the grovernor spring to. put new carburetor on runs wide open was told needed a spring When you removed the other carburetor, you should have also removed 2 cables and the governor spring. One of the cables connects to the choke and the other to the throttle. The governor spring connects from the governor to the free-moving lever on the throttle. Kinda hard to describe without pictures - I suggest going to your local public library and checking out a manual on small engine repair (with luck, they will have a manual for your particular application). At any rate, it's not just ANY governor spring, but the spring designed for your application. Hopefully you didn't lose the old governor spring and you can re-use it if it wasn't damaged or stretched when it was removed.
When an engine experiences high speed governing what happens?
Governors are typically one of three types: Pneumatic: the governor mechanism sense air flow; typical design includes an air vane mounted inside the engine's blower housing and linked to the carburetor's throttle shaft. A spring pulls the throttle open and as the engine gains speed, increased air flow from the blower forces the vane back against the spring, partially closing the throttle. Centrifugal: a flyweight mechanism driven by the engine is linked to the throttle and works against a spring in a fashion similar to that of the pneumatic governor. Electronic: a servo motor is linked to the throttle and controlled by an electronic module that senses engine speed by counting electrical pulses emitted by the ignition system or a magnetic pickup. The frequency of these pulses varies directly with engine speed, allowing the control module to apply a proportional voltage to the servo to regulate engine speed.
How do you check governor on Briggs and stratton engine?
To check the governor on a Briggs and Stratton engine, first, ensure the engine is off and cool. Remove the air filter and locate the governor arm connected to the throttle plate. Manually move the governor arm to see if it returns to its original position, indicating proper function. Additionally, inspect the governor spring for any damage or wear, and verify that the linkage is free of obstructions.
Which governor component applies force to the throttle shaft in an effort to move it to the wide open throttle position?
governed idle spring
On the bottom of the carb on the mag 2000 is there supposed to be a spring on the bottom that holds it in a running position when depressing the throttle?
There is
What do i fix when the lawn mower engine stops 2-3 seconds after it starts unless you continue to prime it?
One thing I have done is check the spring on the throttle. I had this happen and the spring that holds the throttle in a specific location had come unhooked. I simply held the throttle open, had another person sstart the mower and then reattached the spring to hold the throttle open in the desired position.
How do you remove the governor on a John Deere gator 850?
To remove the governor on a John Deere Gator 850, you typically need to access the engine compartment and locate the governor linkage. Disconnect the linkage from the throttle input and remove any retaining clips. You may also need to adjust or remove the governor spring to ensure the engine can reach higher RPMs. Always consult the operator's manual for specific instructions and safety precautions before making modifications.
How do you remove a carburetor from a 4.5hp Briggs and Stratton motor?
(1) Remove the air filter and housing (2) Loosen the cable bracket (3) Remove the throttle and choke cables from the carburetor (4) Remove the governor spring from the carburetor (5) Remove the two bolts that fasten the carburetor to the engine. CAUTION: Do not stretch or bend the governor spring while removing or re-installing.
