Honda Lawn Mower Automatic Choke Problem

Honda lawn mowers are renowned for their reliability and durability. However, even the lawn mowers can have problems from time to time. One common problem that Honda lawn mower owners may encounter is an issue with the automatic choke.

If your Honda lawn mower’s automatic choke is not working properly, it can be a real nuisance. The automatic choke is responsible for automatically adjusting the amount of fuel that is delivered to the engine. If it is not working properly, the engine may run too lean or too rich.

This can cause the engine to run rough, or even stall.

If you’re having trouble with your Honda lawn mower’s automatic choke, you’re not alone. Many Honda owners have reported this problem. The automatic choke is designed to make starting your lawn mower easier.

However, many people have found that it doesn’t always work as it should. There are a few things that you can try if your automatic choke is giving you trouble.

First, make sure that the air filter is clean. A dirty air filter can cause the choke to stick in the “on” position. If the air filter is clean, try adjusting the choke cable. The cable may be too tight or too loose.

Either way, it can cause the choke to stick. If you’re still having trouble, it’s best to take your lawn mower to a Honda dealer or a qualified repair shop. They can diagnose the problem and make the necessary repairs.

Honda Lawn Mower Automatic Choke Problem and Solution

If you own a Honda GCV190 engine, you may have experienced problems with the auto choke feature. The auto choke is designed to automatically engage the choke when the engine is started, and to disengage it when the engine warms up.

However, some owners have reported that the auto choke doesn’t always work properly.

There are a few things that you can do to try to fix this problem. First, make sure that the air filter is clean. A dirty air filter can cause the auto choke to engage too early.

Second, check the carburetor to make sure that it is clean and adjusted properly. A dirty or misadjusted carburetor can also cause problems with the auto choke. If you’ve tried these things and the auto choke still isn’t working properly, you may need to take the engine to a qualified technician for further diagnosis and repair.

In the meantime, you can try starting the engine with the choke engaged. Once the engine is warm, you can slowly disengage the choke. This may not be the most convenient solution, but it will at least allow you to use your engine until the problem can be fixed.

How do you fix an automatic choke on a lawn mower?

If your lawn mower isn’t starting as easily as it used to, or is stalling more frequently, it may be time to take a look at the automatic choke. The automatic choke is a component of the carburetor that helps to regulate the air/fuel mixture that is drawn into the engine. When the engine is cold, the automatic choke closes off the air supply slightly, allowing more fuel to be drawn in.

This enriches the mixture and makes starting the engine easier. Over time, the automatic choke can become gummed up with dirt and debris, causing it to stick in the closed position. This can make starting the engine very difficult.

If your lawn mower’s engine is having trouble starting, especially in cold weather, it’s a good idea to check the automatic choke and see if it needs to be cleaned or replaced. To clean the automatic choke, first remove the air filter cover and set it aside. Then, locate the carburetor and find the automatic choke.

It will be a small, cylindrical component with a wire attached to it. Use a screwdriver to remove the wire, and then unscrew the automatic choke from the carburetor. Once the automatic choke is removed, you can clean it with carburetor cleaner and a soft brush.

Be sure to clean all of the nooks and crannies, as debris can build up in there and cause the choke to stick. Once it’s clean, screw the choke back into place and reattach the wire. If the automatic choke is damaged or otherwise not working properly, it will need to be replaced.

You can purchase a new automatic choke from most auto parts stores or online. Be sure to get the right size and style for your lawn mower’s carburetor. Installing the new choke is simply a matter of reversing the above steps.

How does the auto choke work on a Honda mower?

An auto choke is a feature found on some Honda lawn mowers. It allows the engine to start and run without having to manually adjust the choke each time. This can be a convenient feature, especially if you forget to adjust the choke before starting the engine.

Here’s how it works: When you turn the key to start the engine, the auto choke automatically adjusts the choke based on the current engine temperature. If the engine is cold, the choke will be set to the “full” position.

This allows more air to enter the engine, which helps to start it more easily. As the engine warms up, the choke will gradually open to the “half” position. This allows less air to enter the engine, which helps to improve engine efficiency.

If you need to stop the engine for any reason, the auto choke will automatically return to the “full” position when you restart the engine. This helps to prevent engine flooding. The auto choke feature can be a helpful convenience, but it’s important to remember that it’s not a replacement for proper engine maintenance.

Be sure to check and adjust the choke manually from time to time to ensure that it’s working correctly.

Why does my Honda lawn mower only run on choke?

If your Honda lawn mower only runs on choke, there are a few potential causes. First, the carburetor might be dirty and need to be cleaned. Second, the air filter might be dirty and need to be replaced.

Third, the spark plug might be fouled and need to be replaced. Any of these issues could cause your lawn mower to only run on choke.

Why is my lawn mower choking?

If your lawn mower is choking, it’s likely because the air filter is dirty. A dirty air filter restricts air flow to the engine, which can cause the engine to run rough. To clean the air filter, remove it from the mower and tap it on a hard surface to remove any built-up dirt.

If the filter is really dirty, you can wash it with soap and water. Let the filter dry completely before putting it back in the mower.


If you own a Honda lawn mower, you may have experienced the frustrating problem of the automatic choke not working properly. The choke is designed to help the engine start by providing a richer mixture of fuel and air. However, if the choke is not working correctly, it can make starting the engine very difficult.

In this blog post, I’ve discussed some common causes of this problem and how to fix it. By following this tips you can often fix the problem yourself and avoid an expensive repair bill.
