The primary reason why your lawn mower might be revving too high is that the engine is receiving too much fuel or air. This can be due to various factors, including a clogged air filter, a malfunctioning carburetor, or an issue with the governor.
If the engine will idle but dies at full throttle the main jet in the carburetor may be plugged. You can repair a plugged main jet by cleaning it, replacing the jet, or replacing the carburetor. If you choose to clean or replace the main jet, you will also want to clean the rest of the carburetor.
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.
For a high-revving engine, you want a short stroke, since it means each piston will travel a shorter distance to reach that ideal average speed.
Governor springs hold the throttle in the desired maximum speed.
Lawn equipment (including lawn mowers, lawn tractors, and even trimmers and blowers) is designed to run at full throttle to give the best performance. Your blade will turn faster at higher throttling, which is essential to proper cutting.
While riding mowers operate at somewhat higher speeds of 3,200 RPM to 3,600 RPM, push mowers typically remain at or around 3,000 RPM. The majority of four-stroke lawnmowers run in the 2,800 RPM to 3,600 RPM range.
The most common cause of this revving is either a stuck throttle or the mass airflow (MAF) sensor. This fault should be addressed as soon as possible for normal operation as this revving can become dangerous if the vehicle is allowed to accelerate unintentionally.
An over rev is exactly what is says it is. It is one or many engine revolutions over or above the maximum number of engine revolutions per minute the engine manufacturer has deemed safe. They typically occur in cars that have manual transmissions on down shifts when the road speed and gear tooth ratio are not in sync.
