How to Change the Carburetor Jet in the New Predator 5000 Generator

If you own a Predator 5000 generator and are looking to change the carburetor jet, this article is for you. In this step-by-step guide, we will walk you through the process of changing the jet in your generator's carburetor. We will also discuss whether or not it is necessary to change the jet and the benefits of running propane in your generator.

Tools Needed for the Job

Before we begin, let's gather the tools we will need for this job. You will need a Phillips screwdriver, a flathead screwdriver, a 12 millimeter socket, a fuel line pliers, and a shallow socket (preferably with a stop). Having these tools ready will make the process much smoother.

Preparing the Generator

To start, make sure the generator switch is in the OFF or STOR position. This will ensure your safety while working on the carburetor. Once the switch is in the correct position, let's move on to removing the side panel and air box.

Removing the Side Panel and Air Box

Begin by using a Phillips screwdriver to remove the side panel that houses the carburetor and air box. Set the panel aside in a safe place. Next, we need to drain any remaining fuel in the float bowl or fuel cup.

Draining the Fuel from the Float Bowl

To drain the fuel, place a container underneath the carburetor and use a Phillips screwdriver to open the fuel screw located at the bottom of the carburetor float bowl. Allow the fuel to drain completely and then tighten the screw back up. Be careful not to overtighten and risk breaking the screw.

Removing the Propane Actuator Cable

Now it's time to remove the propane actuator cable. Simply pull up on the cable gently and slide out the little stop inside the actuator lever. This will disconnect the cable from the carburetor.

Removing the Air Box Cover

To create a little extra space, remove the air box cover. This will give you better access to the carburetor and make the process easier.

Removing the Screws underneath the Carburetor

Next, we need to remove the two screws located underneath the carburetor, one on each side of the plunger for the propane actuator. A right-angle screwdriver can be handy for this task. After loosening the screws, remove them by hand, being careful not to drop them.

Removing the Propane Plunger

The propane plunger stops the fuel flow when the propane switch is activated. To remove it, simply slide it out from the actuator lever. Take a moment to inspect and check for any damage before setting it aside.

Replacing the Jet

Now it's time to replace the jet in the pickup tube. Use a flathead screwdriver with a right-angle attachment to loosen the jet by rotating it counterclockwise. Once you feel it catch, remove the screwdriver and use it as a hand screwdriver to drop out the jet.

Installing the Jet

Choose the appropriate jet for your generator's altitude or usage. It is crucial to keep your jets organized to ensure a smooth assembly process. Replace the mixing tube and hold the new jet in place with your finger. Slide the screwdriver into place to secure the jet, making sure it is properly seated.

Tips for Seating the Jet Correctly

When installing brass jets, remember to go clockwise to seat them and tighten them down. Over-tightening or stripping the jets can lead to bigger problems. Don't forget to reinstall the small metal bracket that acts as a plunger stop.

Reassembling the Carburetor

Reassemble the carburetor by reinstalling the propane plunger, the screws underneath the carburetor, and the propane actuator cable. Take your time to make sure each component is correctly installed and snug.

Testing the Generator

Now that the carburetor is reassembled, it's time to test the generator. Turn on the fuel and let it sit for a minute to allow the fuel to fill up. Check for any potential leaks, ensuring the O-ring is correctly placed and the fuel cup is seated properly.

Do You Really Need to Change the Carburetor Jet?

The question arises: do you really need to change the carburetor jet? The answer depends on various factors, such as your elevation and usage of the generator. If you are primarily using the generator at lower altitudes and only occasionally at higher elevations, you may not need to change the jet. It may run a bit rich, resulting in a slight decrease in fuel efficiency and performance, but it should still meet most needs.

Benefits of Running Propane in Your Generator

Running propane in your generator offers some significant benefits. Unlike gasoline, propane does not require any rejetting, making it a convenient option if you frequently change altitudes. Additionally, propane burns cleaner than gasoline, reducing emissions and resulting in a longer-lasting engine. It is also a safer fuel option, as it is less flammable and has a longer shelf life.

Conclusion

Changing the carburetor jet in your Predator 5000 generator is a relatively simple task that can enhance the performance and efficiency of your machine. Follow the steps outlined in this guide, and you'll have a smoothly running generator in no time. Remember to consider your specific needs and usage patterns when deciding whether or not to change the jet. Enjoy the benefits of propane and reliable power generation!
