The John Deere LX178 was produced from 1991 to 1998.
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.
Without a governor, you would need to adjust the throttle manually each time your lawn mower ran across a dense patch of grass. A governor does the job for you by detecting changes in the load and adjusting the throttle to compensate.
It is better to adjust the governor to run slightly higher and cut back on the throttle till needed. Without the governor, you will need the skill to manually drive the engine within its designed safe limits, and respond fast enough to throttle up when needed to prevent stalling. Long grass is not the problem!
The most common reason for a surging lawn mower engine is a blockage in the fuel supply, but there are other possibilities: Bad gas. Bad spark plug. Dirty/faulty carburetor.
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.
