Mr. Garage's Guide to Installing Six Sigma Jet Kit for Predator Generators

Predator generators are well-known for running rich, causing issues like black spark plugs and clogged spark arrestors. If you're facing this common problem, you're not alone. In this guide, we'll explore a solution that can significantly improve the performance of your Predator generator – the Six Sigma Jet Kit.

Understanding the Problem: Predator Generators and Running Rich

Predator generators, including the 3500-watt model, have a factory-installed 76 jet on their carburetors. However, due to the carburetor's poor sealant, these generators tend to run rich, resulting in black spark plugs and spark arrestor clogs. This issue affects the performance and longevity of the generator.

Running rich has been identified as a widespread problem among Predator generators, and it can be frustrating for owners who experience it. However, with the right solution, this issue can be effectively addressed.

Six Sigma Jet Kit: An Arizona Company

Six Sigma Jet Kit is a local Arizona company that specializes in providing jet kits to improve the air-to-fuel ratio and enhance the performance of various engines. They offer a solution specifically designed for Predator generators, which aims to optimize the carburetor's performance and prevent it from running too rich.

The Six Sigma Jet Kit offers different jet sizes, including the commonly used 68 jet. By installing this kit, you can effectively address the rich running issue and improve the overall performance and efficiency of your Predator generator.

The Need for Jet Kit Installation

Installing a jet kit is necessary if you want to optimize your Predator generator's performance. The stock 76 jet is not ideal for achieving the proper air-to-fuel ratio. By swapping it with a jet of the appropriate size, such as the 68 jet from the Six Sigma Jet Kit, you can ensure that your generator runs leaner and more efficiently.

Upgrading to a smaller jet size allows for better combustion of fuel, resulting in reduced carbon buildup and improved power output. With the right jet, you can achieve a cleaner burn and experience better overall performance from your generator.

Tools Required for Installing a Jet Kit

Before you begin the installation process, it's important to gather the necessary tools. Here are the tools you'll need:

1. Socket wrench
2. 10mm socket
3. Flathead screwdriver
4. Hose clamp pliers
5. Glass jar or container for fuel drainage
6. Gloves

Having these tools handy will make the installation process smoother and more efficient. Once you have them, you're ready to start installing the jet kit.

Step-by-Step Guide to Installing a Jet Kit

To install the Six Sigma Jet Kit and improve your Predator generator's performance, follow these step-by-step instructions:

1. Removing the Hose Assembly and Air Filter Box

Use a socket wrench and a 10mm socket to remove the bolts securing the hose assembly and air filter box. This will grant you access to the carburetor for further modifications.

2. Draining the Fuel from the Bowl

Locate the bowl underneath the carburetor. Use a small flathead screwdriver to carefully open the drain and allow the fuel to drain into a glass jar or container. It's crucial to drain the fuel to prevent any spillage or damage during the installation process.

3. Removing the Main Jet

With the bowl empty, use the same flathead screwdriver to unscrew the main jet located in the carburetor. Take note of its size and appearance for future reference.

4. Installing the New Jet and Emulsion Tube

Take the new jet from the Six Sigma Jet Kit and insert it into the carburetor, ensuring it is securely positioned. Additionally, insert the emulsion tube back into its place if it was removed during the process.

5. Reassembling the Carburetor

Once the new jet and emulsion tube are properly installed, reassemble the carburetor by following the steps in reverse. Tighten the bolts on the hose assembly and air filter box to secure them in place.

Congratulations! You have successfully installed the Six Sigma Jet Kit in your Predator generator.

Pre-Start and Load Testing

Before putting the side panel back on, it's essential to perform pre-start and load testing to ensure that everything is functioning correctly. Start the generator in a well-ventilated area and let it run at idle for a few minutes to allow the fuel to refill the carburetor.

Once the generator is running smoothly, connect a load to it, such as a heat gun, and monitor its performance. Observe how the generator handles the load and check for any irregularities in its operation.

Checking the Spark Plug for Optimal Performance

After subjecting the generator to a load, it's crucial to check the spark plug for signs of optimal performance. Remove the side panel again and locate the spark plug. Take it out and examine its condition.

A properly performing generator should have a spark plug that exhibits the right coloration. It should not be overly white or black, indicating a lean or rich running condition, respectively. Ideally, the spark plug should have a clean, tan color, indicating that the generator is running at an optimal air-to-fuel ratio.

Observations and Results

Upon installing the Six Sigma Jet Kit and thoroughly testing the generator, you may observe significant improvements in its performance. The generator's smoother operation, cleaner spark plug, and enhanced fuel efficiency are all positive indicators of a successful installation.

With the correct jet size and improved combustion, your Predator generator will run leaner, preventing carbon buildup and other issues associated with running too rich.

Conclusion

Installing the Six Sigma Jet Kit in your Predator generator can have a transformative effect on its performance. By addressing the running rich issue, this kit enables your generator to run at an optimal air-to-fuel ratio, resulting in improved efficiency and longevity.

Don't let your Predator generator suffer from constant rich running. Take advantage of the Six Sigma Jet Kit and enjoy the benefits of a properly tuned generator. Upgrade to a leaner and more efficient machine today.
