You’re ready to tackle the overgrown grass in your yard, but your Yard Machine lawn mower sputters and refuses to start. You’ve checked the fuel, the spark plug, even made sure the blade isn’t jammed, but still nothing! Maybe you’ve heard the term “choke” thrown around, but you have no idea where it is on your mower, let alone how to use it. Don’t worry, you’re not alone. This guide will break down everything you need to know about the choke on a Yard Machine lawn mower, from its location to its function and how to use it to get your mower running smoothly.
The choke, usually a lever or knob, is typically located on the carburetor of your Yard Machine lawn mower. It’s designed to enrich the fuel-air mixture in the engine, making it easier to start in cold conditions. Let’s dive into the specifics of finding and using the choke on your Yard Machine mower.
Understanding the Choke: A Vital Tool for Starting Cold Engines
The choke is a crucial component in the starting process of a small gasoline engine like the one found in a Yard Machine lawn mower. Engines require a specific ratio of air to fuel to run correctly. When an engine is cold, it struggles to vaporize the fuel efficiently. This results in a lean mixture that makes starting difficult. The choke comes into play to remedy this issue.
By restricting air intake, the choke increases the concentration of fuel in the air-fuel mixture. This rich mixture is easier to ignite, allowing the engine to start and warm up. As the engine warms up, the fuel vaporizes more readily, and the choke can be released to restore the proper air-fuel ratio for normal operation.
Finding the Choke on Your Yard Machine Lawn Mower
The location of the choke on your Yard Machine lawn mower depends on the specific model. However, it’s typically situated on or near the carburetor. Here’s a step-by-step guide to help you locate it:
1. Identify the Carburetor:
The carburetor is a complex component responsible for mixing air and fuel. It is often found on top of the engine, near the air filter. Look for a metal housing with various tubes and connections.
2. Locate the Choke Lever or Knob:
- Lever: Look for a small lever, often with an arrow or a “choke” inscription, protruding from the carburetor.
- Knob: You may find a small knob, often with a similar inscription, that turns to activate the choke.
3. Consult Your User Manual:
If you’re still struggling to find the choke, your owner’s manual is your best resource. It contains detailed illustrations and explanations of your specific model, including the choke’s location and operation.
How to Use the Choke on Your Yard Machine Lawn Mower
Once you’ve located the choke, using it is relatively straightforward:
1. Engage the Choke:
- Lever: Move the lever to the “choke” position, often indicated by an arrow pointing towards the closed position.
- Knob: Turn the knob clockwise to close the choke.
2. Start the Engine:
Follow the regular starting procedure for your lawnmower, pulling the starter cord until the engine catches.
3. Disengage the Choke Gradually:
Once the engine is running, you can start to gradually disengage the choke.
- Lever: Slowly move the lever back to the “run” position.
- Knob: Gradually turn the knob counterclockwise.
4. Monitor Engine Performance:
Watch for signs that the engine is running smoothly. If it sputters or stalls, you might need to engage the choke slightly again.
Troubleshooting Choke Issues
Even with a properly located and functioning choke, you might encounter issues getting your Yard Machine lawn mower started. Here are some common problems and solutions:
1. Choke Stuck in the Closed Position:
If the choke lever or knob is stuck in the closed position, the engine will be constantly receiving a rich fuel mixture. This can cause difficulty starting and poor performance.
- Solution: Try gently moving the lever or knob, ensuring it moves freely. If it’s stuck, you may need to apply some lubricant or use a small tool to pry it open.
2. Choke Not Engaging Properly:
If the choke isn’t engaging correctly, the fuel-air mixture will remain lean, making it difficult to start the engine.
- Solution: Check the choke mechanism for any signs of damage or wear. If necessary, replace the choke or seek professional assistance.
3. Flooded Engine:
If you’ve tried starting the engine with the choke engaged for too long, you might flood the engine with fuel. This can prevent it from starting.
- Solution: To clear a flooded engine, let it sit for a few minutes to allow any excess fuel to evaporate. Then, try starting it without the choke engaged.
Tips for Using the Choke Effectively
1. Engage the Choke Only When Needed:
The choke should only be used when the engine is cold. As the engine warms up, the choke should be disengaged gradually.
2. Be Patient:
Starting a cold engine can take a few tries. Don’t be discouraged if it doesn’t start immediately.
3. Avoid Over-Choking:
Engaging the choke for too long can flood the engine and make it harder to start.
4. Monitor Engine RPMs:
Once the engine is running, observe the engine speed. If the RPMs are too high or too low, you may need to adjust the choke accordingly.
5. Consult the Owner’s Manual:
Your Yard Machine lawn mower’s owner’s manual provides specific instructions on how to use the choke for your model.

FAQs
Where is the choke on a Yard Machine lawnmower?
The choke on a Yard Machine lawnmower is typically located on the carburetor, a small metal cylinder attached to the engine. It’s usually a lever or knob that you pull or turn to activate the choke. The exact location might vary slightly depending on the specific model, but it will generally be easily accessible near the engine.
To find it, look for a small lever or knob near the carburetor, often marked with a symbol resembling a partially closed circle or the word “choke.”
What does the choke do on a Yard Machine lawnmower?
The choke on a Yard Machine lawnmower helps the engine start easily, especially when it’s cold. When you pull or turn the choke lever, it restricts the flow of air into the carburetor, causing the engine to run richer (with more fuel and less air). This creates a denser, more combustible mixture that ignites more easily, allowing the engine to start and warm up.
Once the engine has started and warmed up, you should gradually release the choke. If you leave it engaged, it can cause the engine to run too rich, leading to poor performance and potentially damaging the engine.
How do I use the choke on a Yard Machine lawnmower?
To use the choke on a Yard Machine lawnmower, you’ll need to follow these simple steps:
- Pull the choke lever or turn the choke knob to the “on” position. This restricts the airflow and enriches the fuel mixture.
- Start the engine.
- Once the engine starts, gradually release the choke. You can do this by slowly pushing the lever back to the “off” position or turning the knob back to the starting position.
- Continue to run the engine for a few minutes with the choke off until it warms up.
When should I use the choke on a Yard Machine lawnmower?
You should use the choke on a Yard Machine lawnmower when starting the engine cold. The choke makes it easier for the engine to start when the fuel is cold and less volatile. It’s generally not necessary to use the choke when the engine is warm, as it should start easily without it.
