So, what are the Kohler 7000 series smart choke problems? These are choke stickiness and power loss. To resolve the issues, you may need to inspect the fuel filter, air vane, torsion spring, and other associated motor parts.

Here, we will discuss the most prevalent Kohler 7000 series smart choke issues and potential fixes. Preventative measures will also be introduced. So keep an eye on this site!

What is Smart Choke in Kohler Engine?

Smart Choke is a feature found in some Kohler engines that automates the choke operation during engine startup. The purpose of the choke is to restrict the airflow to the engine, making the fuel mixture richer and easier to ignite in cold conditions.

The Smart Choke system works by using an automatic choke control module to sense the engine’s temperature and adjust the choke accordingly. During engine startup, the module activates the choke to provide a rich fuel mixture for easy ignition. 

Once the engine starts, the module gradually opens the choke to increase the airflow and decrease the fuel mixture. Which eventually allows the engine to run smoothly. The Smart Choke system also includes a manual override, which allows the operator to control the choke manually if necessary.

Please keep in mind that the following are some frequent assumptions. Other issues that you may encounter are possible. If you discover any further issues, act accordingly.

Problem 1: Smart Choke isn’t Started

One of the most common problems with the Kohler 7000 series engine is when the smart choke is only partially started or not started at all. Several issues, including a disturbed air vane, wiring problems, or a faulty thermostat can cause this.


If you are experiencing this issue, follow these steps to troubleshoot the problem:

  • Check the air vane and thermostat: Start by checking the air vane and thermostat for any visible signs of damage or wear. If you notice any issues, replace the damaged components.
  • Inspect the torsion spring and linkage: The torsion spring and linkage are essential components of the smart choke system. So make sure they are functioning properly. If you notice any issues with these parts, it’s best to have them inspected by a professional mechanic.
  • Check the wiring: Make sure the wiring is properly connected and not damaged. If you notice any loose or damaged wires, fix them before attempting to start the engine.
  • Lastly, it is recommended to go through the service manual provided by the manufacturers and bring it to a technician.

Problem 2: Power Loss

In this case, the cause might be a faulty thermostat inside the smart choke and oil pressure switch. According to the working mechanism, the oil pressure switch is always on. A dirty or clogged fuel filter can cause the engine to loss power.

When oil pressures proceed inside the engine, the switch gets stopped and the thermostat receives the positive battery power from the oil pressure switch. So, if the thermostat gets damaged or clogged, power loss may occur. 


Going through the following steps can be helpful in that circumstances.

  • Step 1: Check the air filter and replace it if it is dirty or clogged.
  • Step 2: Also, check the thermostat with a fused jumper to see whether it is working or not.
  • Step 3: Clean the carburetor to remove any dirt or debris.
  • Step 4: Check the fuel supply and ensure enough fuel is in the tank.
  • Step 5: Replace the spark plug if it is damaged or worn out.
  • Step 6: It is always wise to have it checked by a technician. 

However, it is very tough to identify the particular problem of your Kohler 7000 smart choke. But in general, these are all the general troubleshooting that you may apply if you are facing the issues.

Preventative Measures for Kohler 7000 Series Smart Choke Problems

There are certain preventative actions you may take to keep your Kohler 7000 series smart choke engine working properly.

Here are a few tips:

  • Regular Maintenance: Regularly scheduled maintenance, such as oil changes, spark plug replacements, and air filter cleanings. These can help prevent many common problems that may occur.
  • Clean the air filter: A dirty air filter can cause the engine to struggle to breathe, leading to a host of issues. Cleaning the air filter regularly can help prevent this.
  • Use clean fuel: Dirty or stale fuel can cause the engine to run poorly or not start at all. Be sure to use fresh, clean fuel in your engine.
  • Check the fuel filter: A clogged fuel filter can prevent the engine from receiving enough fuel to run properly. Check the fuel filter regularly.
  • Avoid steep hills and angles: The Kohler 7000 series engine can only handle up to a 25-degree angle at best. So try to avoid steep hills and angles that may cause the engine to strain.

Final Thoughts

Even the most advanced and high-tech engines, like the Kohler 7000 series, can encounter problems from time to time. By following the troubleshooting steps and solutions provided in the service bulletin, you may resolve the issues. 

Initially, cleaning the air filter and fuel filter can be beneficial. However, by taking preventative measures, the problems can be avoided. Also, using clean fuel and avoiding steep hills and angles is wise, as per experts’ assumptions.
