Yardmachines push mower won’t stay running is a common problem that can be caused by a number of factors. The most common causes include:
- A dirty carburetor
- A faulty spark plug
- A clogged fuel filter
- A bad fuel pump
- A loose or damaged ignition coil
If your Yardmachines push mower won’t stay running, it is important to troubleshoot the problem and make the necessary repairs. Otherwise, you may end up damaging the mower or causing it to become unsafe to operate.
Here are some tips for troubleshooting a Yardmachines push mower that won’t stay running:
- Check the carburetor for dirt and debris. If the carburetor is dirty, it may need to be cleaned or replaced.
- Check the spark plug for wear or damage. If the spark plug is worn or damaged, it may need to be replaced.
- Check the fuel filter for clogs. If the fuel filter is clogged, it may need to be cleaned or replaced.
- Check the fuel pump for proper operation. If the fuel pump is not working properly, it may need to be replaced.
- Check the ignition coil for loose or damaged wires. If the ignition coil is loose or damaged, it may need to be repaired or replaced.
If you are unable to troubleshoot the problem yourself, you may need to take your Yardmachines push mower to a qualified repair technician.
1. Fuel
When troubleshooting a Yardmachines push mower that won’t stay running, it is important to consider the fuel system. The fuel system consists of the fuel tank, fuel line, fuel filter, and carburetor. If any of these components are not functioning properly, it can cause the mower to run erratically or stall.
One of the most common causes of a Yardmachines push mower not staying running is a lack of fuel. If the fuel tank is empty or the fuel line is clogged, the mower will not be able to get the fuel it needs to run. It is also important to use fresh fuel in your mower. Old fuel can gum up the carburetor and cause the mower to run poorly.
Another common cause of a Yardmachines push mower not staying running is a dirty fuel filter. The fuel filter is designed to remove dirt and debris from the fuel. If the fuel filter is clogged, it can restrict the flow of fuel to the carburetor and cause the mower to stall.
If you are experiencing problems with your Yardmachines push mower not staying running, it is important to check the fuel system. Make sure that the fuel tank is full, the fuel line is clear, and the fuel filter is clean. If you are still having problems, you may need to take your mower to a qualified repair technician.
2. Spark
The spark plug and ignition coil play a crucial role in the operation of a Yardmachines push mower. The spark plug is responsible for creating the spark that ignites the air-fuel mixture in the combustion chamber. The ignition coil provides the high-voltage current that is needed to create the spark. If either of these components is not functioning properly, it can cause the mower to run erratically or stall.
A dirty or fouled spark plug can prevent the spark from jumping across the gap between the electrodes. This can cause the mower to misfire or stall. A spark plug that is not gapped correctly can also cause problems. The gap between the electrodes should be set to the manufacturer’s specifications. If the gap is too wide, the spark may not be strong enough to ignite the air-fuel mixture. If the gap is too narrow, the spark may not be able to jump across the gap at all.
A faulty ignition coil can also prevent the spark plug from creating a spark. The ignition coil is responsible for providing the high-voltage current that is needed to create the spark. If the ignition coil is not functioning properly, it may not be able to provide enough voltage to create a spark. This can cause the mower to stall or run erratically.
If you are experiencing problems with your Yardmachines push mower not staying running, it is important to check the spark plug and ignition coil. Make sure that the spark plug is clean and gapped correctly. Also, check the ignition coil to make sure that it is functioning properly. If you are not sure how to do this, you can take your mower to a qualified repair technician.
3. Air
A clean air filter and a properly adjusted carburetor are essential for the smooth operation of a Yardmachines push mower. The air filter prevents dirt and debris from entering the carburetor and the combustion chamber. A dirty air filter can restrict the flow of air to the carburetor, which can cause the mower to run lean and stall. A carburetor that is not adjusted correctly can also cause the mower to run poorly or stall.The following are some of the signs and symptoms of a dirty air filter or a carburetor that is out of adjustment:
- The mower is difficult to start.
- The mower runs erratically or stalls.
- The mower does not have as much power as it used to.
- The mower is using more fuel than usual.
- The mower is emitting black smoke from the exhaust.
If you are experiencing any of these problems, it is important to check the air filter and the carburetor. To check the air filter, simply remove it from the mower and inspect it for dirt and debris. If the air filter is dirty, it can be cleaned with a mild detergent and water. To check the carburetor, you will need to remove it from the mower and inspect it for any signs of damage or wear. If the carburetor is damaged or worn, it will need to be replaced.
It is also important to make sure that the carburetor is adjusted correctly. The carburetor is responsible for mixing the air and fuel together in the correct proportions. If the carburetor is not adjusted correctly, the mower will not run properly. To adjust the carburetor, you will need to consult your mower’s owner’s manual.
4. Compression
Compression is essential for a Yardmachines push mower to run properly. Compression is the force that drives the piston down in the cylinder, which in turn creates the power that drives the mower. If the compression is too low, the mower will not have enough power to run properly and may stall.
There are two main components that can affect the compression in a Yardmachines push mower: the compression release valve and the valves. The compression release valve is a small valve that is located on the cylinder head. The purpose of the compression release valve is to release some of the compression when the mower is starting. This makes it easier to pull the starter cord and get the mower running.
The valves are located on the cylinder head and control the flow of air and fuel into and out of the cylinder. If the valves are not adjusted correctly, they can cause the compression to be too low or too high.
If you are experiencing problems with your Yardmachines push mower not staying running, it is important to check the compression. You can do this by removing the spark plug and inserting a compression tester into the spark plug hole. The compression should be between 80 and 120 psi. If the compression is too low, you may need to adjust the compression release valve or the valves.
5. Electrical
The electrical system is a critical component of any Yardmachines push mower. The battery provides the power to start the mower and run the electrical components, such as the ignition system and the headlights. The electrical connections must be clean and tight to ensure that the electrical current can flow properly. If there is a problem with the electrical system, it can cause the mower to not stay running.

Battery
A weak or dead battery can prevent the mower from starting or cause it to stall. It is important to keep the battery charged and to replace it if it is old or damaged.
-
Electrical Connections
Loose or corroded electrical connections can also cause the mower to not stay running. It is important to check the electrical connections and to clean or tighten them if necessary.
If you are experiencing problems with your Yardmachines push mower not staying running, it is important to check the electrical system. By troubleshooting the battery and the electrical connections, you can often identify and fix the problem yourself. However, if you are unable to resolve the issue, it is best to consult with a qualified repair technician.
Conclusion
If your Yardmachines push mower won’t stay running, there are a number of potential causes. By troubleshooting the fuel system, spark plug and ignition coil, air filter and carburetor, compression, and electrical system, you can often identify and fix the problem yourself. However, if you are unable to resolve the issue, it is best to consult with a qualified repair technician.
By following the tips in this article, you can keep your Yardmachines push mower running smoothly and efficiently for many years to come.
