How to Change Your Generator's Carburetor

How to Change Your Generator's Carburetor

The following video and step by step instructions will teach you how to change your generator's carburetor. Make sure your generator is off before starting and never perform maintenance on a running generator. Make sure the fuel valve is in the OFF position to stop the flow of fuel to the carburetor.

Be sure to refer to your operator's manual for specific instructions for your generator. This guide should be used as a source for additional information; not as an alternative to the manual. If you have any additional questions, feel free to contact us.

Removing Your Carburetor

Note: The carburetor is located in the back of the generator just behind the air filter assembly.

1. Locate the air filter assembly to the left of the recoil starter. Remove the cover by unscrewing the knob located at the bottom of the air cleaner. Pull up on the bottom of the cover and slide it off the top two tabs.

2. Remove the foam air filter from the housing. Warning: the foam filter is probably somewhat oily.

3. After removing the foam, remove the metal grate from the air filter housing. It is held into position by two plastic pins. Pull the grate straight off the pins to remove it.

4. Once the grate has been removed, remove the three nuts that are holding the air filter housing in place and set them to the side. Remove the following nuts:

    • Nut 1: Located in the middle of the air filter housing.
    • Nut 2: Located on the top left hand side of the air filter housing.
    • Nut 3: Located at the bottom, backside of the air filter housing.

    5. Detach the rubber hose on the left hand side of the air filter assembly. Use a pair of pliers to remove the clamp holding it in place before sliding off the hose.

    6. Detach the rubber hose on the top of the air filter assembly, by pulling the hose from the housing. The air filter assembly should be completely free. Slide the entire casing off of the body of the generator to gain full access to the carburetor.

    7. Unclip the hose attached to the right hand side of the carburetor. You may need to use pliers or some other type of tool in order to pry the hose free.

    8. Remove the gasket from the front of the carburetor by simply sliding it off of the bolts. Set it aside for the replacement carburetor.

    9. Pull the old carburetor forward along the bolts until the regulating spring connected to the top of the mechanism becomes taut. Carefully unlink the regulating spring from the carburetor.

    10. Remove the pulling rod by swinging the linkage all the way to the right and pulling up on the rod. Once both the regulating spring and the pulling rod have been disconnected, the carburetor can be fully removed.

            Installing Your Carburetor

            1. Before installing your new carburetor, make sure to first attach the choke lever. Once that is done, slide the replacement carburetor back into the position of the old one.

            2. Connect the pulling rod and the regulating spring to the top of the mechanism.

            3. Put the gasket back in place and and reattach the fuel hose to the right hand side of the carburetor. Clamp it in place and slide the air filter housing back onto the generator.

            4. Reattach your the three nuts you previously set aside:

              • Nut 1: Located in the middle of the air filter housing.
              • Nut 2: Located on the top left hand side of the air filter housing.
              • Nut 3: Located at the bottom, backside of the air filter housing.

            5. Plug both of the hoses back in. Use a pair of pliers to secure the clamp on the hose leading into the left hand side of the air filter housing. The hose on top can be fed in without any tools.

            6. Replace the metal grate, making sure that it fits securely onto its intended two threads. This is very important, as it prevents the foam filter from being sucked into the carburetor.

            7. Fit the foam filter back into the housing. Once it is nice and secure, close up the casing with the air filter assembly cover.
