Riding mowers are an essential tool for those who maintain large amounts of grass, such as commercial lawn care businesses or large private yards. To ensure these machines run properly, you must use the choke and throttle to adjust the engine speed. In this article, we will discuss how to use choke and throttle on riding mowers.
What Is a Choke and Throttle?
The choke and throttle are two separate parts of the engine that work together to control the engine speed. The choke is a valve that restricts the airflow into the carburetor, which lowers the engine speed. The throttle, on the other hand, is a valve that increases the airflow, which raises the engine speed. The choke and throttle are usually located near the carburetor and can be easily accessed for adjustments.
How to Use Choke and Throttle on Riding Mowers
When starting a riding mower, the choke should be set in the “on” position. This restricts the airflow, which makes it easier for the engine to start. When the engine is running, the choke should be slowly adjusted back to the “off” position. This will allow more air to flow into the carburetor and will raise the engine speed.
The throttle can be used to further adjust the engine speed. When the throttle is in the “on” position, more air is allowed to flow into the carburetor and the engine will run faster. When the throttle is in the “off” position, the engine will run slower. It is important to note that the throttle should never be set to the “off” position when the engine is running, as this could cause the engine to shut off.
When adjusting the choke and throttle, it is important to adjust them slowly and carefully. If the adjustments are made too quickly, the engine could shut off or become damaged. It is also important to keep an eye on the engine temperature. If the engine becomes too hot, it could cause serious damage.
Conclusion
The choke and throttle are two separate components of the engine that work together to control the engine speed. When starting a riding mower, the choke is set in the “on” position and then slowly adjusted back to the “off” position when the engine is running. The throttle can then be used to further adjust the engine speed. It is important to adjust the choke and throttle slowly and carefully and to keep an eye on the engine temperature.
Frequently Asked Questions
What is the purpose of a choke?
The purpose of a choke is to restrict the airflow into the carburetor, which lowers the engine speed. This makes it easier for the engine to start.
What is the difference between a choke and a throttle?
The choke is a valve that restricts the airflow into the carburetor, while the throttle is a valve that increases the airflow. The choke lowers the engine speed, while the throttle increases it.
Where is the choke and throttle located?
The choke and throttle are usually located near the carburetor and can be easily accessed for adjustments.
Can I adjust the choke and throttle while the engine is running?
Yes, you can adjust the choke and throttle while the engine is running. However, it is important to adjust them slowly and carefully.
What happens if I set the throttle to the “off” position when the engine is running?
Setting the throttle to the “off” position when the engine is running can cause the engine to shut off.
What should I do if the engine becomes too hot?
If the engine becomes too hot, you should turn it off and let it cool down before restarting it.
How often should I check the choke and throttle settings?
It is a good idea to check the choke and throttle settings regularly to ensure that they are properly adjusted.
Is it dangerous to adjust the choke and throttle?
If the choke and throttle are adjusted too quickly, it could cause the engine to shut off or become damaged. Therefore, it is important to adjust them slowly and carefully.
