Governor On Small Engine: Everything You Need To Know In 2023

How Small Engine Governors Work (any governor setup) YouTube from www.youtube.com

The governor on a small engine is a crucial component that regulates the speed of the engine. It ensures that the engine runs at a constant speed, regardless of the load applied to it. Without a governor, the engine would run at full speed, leading to damage and inefficiency. In this article, we will discuss everything you need to know about the governor on a small engine, including its function, types, maintenance, and troubleshooting tips.

What is a Governor on Small Engine?

A governor on a small engine is a device that controls the speed of the engine. It is typically found on small engines such as lawnmowers, generators, and small boats. The governor works by monitoring the engine speed and adjusting the throttle accordingly. If the engine speed drops, the governor will increase the throttle to maintain a constant speed. Conversely, if the engine speed increases, the governor will reduce the throttle to maintain the desired speed. The governor ensures that the engine runs at a constant speed, regardless of the load applied to it.

Types of Governor on Small Engine

There are two main types of governors on small engines: mechanical and electronic. Mechanical governors are the most common type and use a mechanical linkage to control the throttle. The linkage is connected to the carburetor and the governor arm. As the engine speed changes, the governor arm moves, which in turn moves the throttle. Electronic governors, on the other hand, use electronic sensors and a control module to regulate the engine speed. They are more complex and expensive than mechanical governors but offer more precise speed control.

Maintenance of Governor on Small Engine

Regular maintenance of the governor on a small engine is essential to ensure proper operation and longevity. The governor should be inspected and serviced every 50 hours of operation or at least once a year. Here are some maintenance tips for the governor:

Check the Governor Linkage

The governor linkage should be checked for wear and proper adjustment. The linkage should move smoothly without any binding or sticking. If the linkage is worn or damaged, it should be replaced.

Clean the Governor Components

The governor components should be cleaned with a solvent to remove any dirt or debris. The linkage and spring should be lubricated with a light oil to ensure smooth operation.

Inspect the Governor Spring

The governor spring should be inspected for wear and proper tension. If the spring is worn or damaged, it should be replaced. The tension of the spring should be checked and adjusted if necessary.

Troubleshooting Governor on Small Engine

If the governor on your small engine is not working correctly, there are a few troubleshooting tips you can try before taking it to a professional. Here are some common issues and solutions:

Engine Runs Too Slow

If the engine runs too slow, the governor spring may be loose or broken. Check the spring tension and adjust or replace if necessary.

Engine Runs Too Fast

If the engine runs too fast, the governor linkage may be binding or sticking. Check the linkage for wear or damage and lubricate if necessary.

Engine Surges or Hunts

If the engine surges or hunts, the governor may be out of adjustment or the carburetor may be dirty. Adjust the governor linkage or clean the carburetor to solve the issue.

Conclusion

In conclusion, the governor on a small engine is a critical component that regulates the engine's speed. Regular maintenance and troubleshooting are necessary to ensure proper operation and longevity. By following the tips outlined in this article, you can keep your small engine running smoothly for years to come.
