How Mechanical Governors Work. A mechanical governor uses flyweights to create a force based off of crankshaft speed which is balanced by the force of the governor spring. The top engine speed is varied by increasing the spring force to run faster or decreasing the force to run slower.
To raise the pressure settings, turn the adjusting screw counter-clockwise. To lower the pressure settings, turn the adjusting screw clockwise. Note: Be careful not to over adjust. Each 1/4 turn of the adjusting screw raises or lowers the pressure setting approximately 4 psi.
The governor system is like a cruise control system. It maintains the speed of your lawn mower or outdoor power products. When Briggs & Stratton governors are adjusted properly, they keep your speed steady regardless of engine load – the amount of work the engine must perform.
Symptoms can include: The engine idling too fast or not idling down when the throttle lever is moved to idle position. Surging (overrevving). The engine not being able to reach top speed.
The governor is usually attached directly to the compressor. The inlet port connects the governor to the air reservoir it regulates. As the air pressure in the reservoir increases, the piston and inlet/exhaust valve shifts up against the resistance of the pressure setting spring.
You can change how sensitive the mechanical governor system responds to loads by changing the amount of leverage your governor spring applies to the governor arm. The pivot point is where the governor arm meets the governor cross shaft.
Symptoms can include: The engine idling too fast or not idling down when the throttle lever is moved to idle position. Surging (overrevving). The engine not being able to reach top speed.

I have a Crafstman Riding mower model #917.273643. That ran fine one second, I shut it off for five minutes. When I went to start it back up it wouldn’t start. Cranks fine, checked the wires, fuse, and spark plug. The plug was dirty so I cleaned it. But I am not getting any spark. I bought a new plug still no spark. I also checked the plug on another motor and I had spark so the plug wasn’t bad. Any suggestions on how to troubleshoot this or what may be wrong?

Lawn mower cranck but wont start…
ANSWER : Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.

Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.
