Introduction

In this article, we will be discussing how to modify a Predator 8750 generator by changing its carburetor from fuel to a biofuel carb. The purpose of this modification is to allow the generator to run on both propane and gas, thereby providing greater flexibility in fuel options. We will guide you through the step-by-step process of removing the old carburetor, installing the new one, and making necessary modifications to the air intake system.

Background Information

The Predator 8750 generator is a popular choice among homeowners and contractors due to its reliability and high power output. However, it is originally designed to run on traditional fuel, which may not be the most environmentally friendly option. By converting it to a biofuel carburetor, you can reduce emissions and have the option to use propane as an alternative fuel source.

Why Modify the Generator?

Modifying the generator to run on a biofuel carburetor offers several advantages. Firstly, it allows you to use propane, a cleaner-burning fuel, which reduces emissions and decreases your carbon footprint. Additionally, having the ability to switch between propane and gas provides flexibility, especially in situations where one fuel source may be more readily available than the other. Furthermore, using propane can result in cost savings, as propane is often cheaper than gasoline.

Tools and Materials Needed

Before starting the modification process, there are a few tools and materials you will need:

1. New biofuel carburetor
2. Gasket set (if not included with the carburetor)
3. Screwdriver set
4. Pliers
5. Wrench
6. Headlamp (optional, for better visibility)
7. Quarter-inch brass fitting and hose (if necessary for air intake modification)
8. Five-minute epoxy (if necessary for air intake modification)
9. Dremel tool (if necessary to shave a small amount of material)

Step 1: Removing the Air Box

The first step in the modification process is to remove the air box. The air box is held in place by screws connected to the carburetor, as well as an additional screw at the back. Use a screwdriver to loosen and remove these screws. Once the screws are removed, the air box can be opened and lifted out.

Step 2: Disconnecting the Fuel Hoses

Next, you will need to disconnect the fuel hoses from the carburetor. Start by removing the grip to expose the two 10 millimeter bolts that secure the air box to the carburetor. There may also be an attachment to the fuel hose that needs to be separated. Carefully disconnect these hoses, ensuring that the fuel is turned off beforehand.

Step 3: Removing the Carburetor

Now that the air box and fuel hoses are detached, it's time to remove the old carburetor. Use a wrench to remove the two 10 millimeter bolts that hold the carburetor in place. Once the bolts are removed, the carburetor can be pulled away from the generator.

Step 4: Installing the New Carburetor

With the old carburetor removed, it's time to install the new biofuel carburetor. Before doing so, remove the old gasket (unless you prefer to use the new ones provided with the gasket set). Slide the new carburetor into place, ensuring that it aligns with the corresponding gaskets on the back and front. Secure the new carburetor with the bolts that were removed earlier.

Step 5: Dealing with the Air Intake Modification

For owners of the 2020 Predator 8750 model, there may be a modification needed due to changes in the air intake system. If the new carburetor does not fit due to an obstruction, such as a nipple, you will need to find a workaround. This may involve cutting off the nipple, adding a brass fitting, and attaching a hose to ensure proper airflow. Make sure to seal any holes and ensure that the modification is flush and covered.

Step 6: Reassembling the Generator

Once the carburetor and air intake modifications are complete, it's time to reassemble the generator. Put the air box back in place and tighten the bolts securely. Reattach the fuel hoses and ensure that the connections are tight. Double-check all the components to make sure nothing is bent or interfering with the operation of the generator.

Testing and Final Thoughts

After completing the reassembly, it's time to test the modified generator. Connect it to a propane tank, open the tank, and prime the generator with propane. Once everything is set up, start the generator and ensure that it runs smoothly on propane. Take note of any improvements in performance or fuel efficiency compared to running it on traditional fuel. Overall, modifying the Predator 8750 generator to run on a biofuel carburetor offers environmental benefits, fuel flexibility, and potential cost savings.
