How to Clean the Carburetor and Drain the Fuel System of a Honda Generator

If you own a Honda generator, it's important to know how to properly clean the carburetor and drain the fuel system to maintain its performance and longevity. In this step-by-step guide, we will walk you through the process of cleaning the carburetor and draining the fuel system of a Honda generator EU 2000I. But before we get started, let's gather the tools you will need for this task.

Tools needed for cleaning the carb and draining the fuel system

• Flathead screwdriver
• Pliers
• Small flathead screwdriver
• Eight-millimeter socket with ratchet
• Fuel line clamps

Now that we have our tools ready, let's begin by preparing the generator for repair.

3. Preparing the generator for repair

Before performing any repairs on the fuel system, it's important to turn off the fuel valve to prevent any spills. Locate the fuel cap on top of the generator and turn the valve to the "off" position. This will ensure that no fuel leaks out during the repair process.

4. Removing the air filter and air filter housing

To access the carburetor, we first need to remove the air filter and air filter housing. Start by using a flathead screwdriver to remove the access panel on the side of the generator. Then, remove the screw on the front of the air filter cover and take off the cover to expose the air filter. Remove the air filter and the lower filter from inside the air filter cover.

Inside the air filter cover, you will find an eight-millimeter screw that needs to be removed, as well as two eight-millimeter screws that hold the air filter housing and carburetor to the engine. While removing the air filter housing, be careful with a small black breather hose that runs from the crankcase up to the air cleaner. Remove that hose before you can take off the air cleaner.

5. Disconnecting the fuel line

Before removing the carburetor, we need to disconnect the fuel line from the fuel pump to the carburetor. Use your fuel line pliers to clamp off the fuel line to prevent any fuel from flowing. Then, remove the small clamp that holds the fuel line to the carburetor. Be prepared to catch any fuel that may leak out when removing the fuel line. Also, remove the air filter gasket and check for any damages. If there is a rip in the gasket, it is recommended to replace it.

6. Removing the carburetor and inspecting the gasket

To remove the carburetor, we first need to drain the fuel bowl. Place a drain pan beneath the carburetor and use a small flathead screwdriver to open the drain screw at the bottom of the carburetor. As you turn the screw out, fuel will start to flow out of the carburetor and into the drain pan. Once the fuel has drained out, you can move the carburetor away from the engine.

Inspect the gasket between the carburetor and the engine for any damage. If necessary, replace the gasket to ensure a proper seal.

7. Draining the fuel bowl and cleaning the carburetor

With the carburetor removed, we can now focus on cleaning it. Start by removing the 10-millimeter bolt at the bottom of the fuel bowl. Hold the carburetor over a drain tank and remove the bolt. Be aware that there may still be some fuel left in the bolt, so be prepared to catch it. Once the bolt is removed, inspect the fuel bowl for any varnish or debris and clean it as necessary.

Next, remove the float pin and float from the carburetor. You will notice a needle on a spring that controls the flow of fuel into the carburetor. Inspect it for any damage or debris. There is a gasket that seals the flow bowl to the carburetor body, so make sure to remove and replace it if needed.

Inside the main tube of the carburetor, you will find the main jet. This jet controls the flow of fuel into the engine. Inspect it for any debris or varnish and clean it thoroughly with carb cleaner and compressed air.

Continue cleaning the carburetor by flushing out any dirt or debris from the inlet needle and the air surfaces on the front and back of the carburetor. Use carb cleaner and compressed air to ensure a thorough cleaning.

Once the carburetor is completely clean, you are ready to reassemble it.

8. Reassembling the carburetor

During the reassembly process, pay attention to the order in which the parts were removed. Start by inserting the needle in its correct position, followed by the main jet. Make sure the flathead part of the main jet is inserted last, allowing you to tighten it back down with a screwdriver.

Reinstall the gasket for the flow bolt and make sure it is seated properly in the groove of the carburetor. Check the float and clean or replace the needle inlet if necessary. Place the carburetor back onto the engine and reattach the fuel lines and wires for the electronic throttle control. Don't forget to reinstall the gasket between the carburetor and the air filter.

9. Reinstalling the carburetor and checking for leaks

Before fully reassembling the generator, reconnect the wires for the electronic throttle control and ensure that the gasket between the carburetor and the air filter is in place. Reinstall the fuel lines and adjust the drain hose so it protrudes just a little bit at the bottom of the housing.

Once everything is in place, install the air filter cover, making sure to attach the breather hose to the nipple at the bottom. Check the air filters for cleanliness and reinstall them into the housing.

Before putting the access panel back on, turn on the fuel valve and check the carburetor for any leaks. Visually inspect everything to make sure nothing is leaking inside the cover. Once you've confirmed there are no leaks, you can put the access panel back on or start the generator.
