Upgrading to an Edelbrock carburetor is an excellent way to enhance your vehicle’s power and efficiency while ensuring reliability. However, to fully take advantage of all its benefits, you must know how to clean an Edelbrock carburetor. Keeping the carb clean and moving freely will ensure many years of top-quality performance.
Over time, your Edelbrock carburetor will develop fuel deposits from additives, contaminants, and evaporation, which can cause blockages, seizing, and other issues affecting your carb’s – and engine’s – performance. If you live in an area with exceptionally high humidity or regular extreme temperature fluctuations, condensation inside the carb can cause deposits and even corrosion. Knowing how to clean Edelbrock carburetor metering jets, metering rods, needle and seats, internal passageways, and the carb itself will help you eliminate these contaminants and keep your vehicle running smoothly for a long time.
Preparing Your Carburetor For Cleaning
Before cleaning an Edelbrock carburetor, you must know how to prepare it properly. Removing and disassembling the carb correctly will ensure that everything will fit back together and work as it should once the cleaning is done. You should have a workbench or flat surface handy and a selection of small brushes, rags, wrenches, and sockets. You’ll also need a can of carburetor cleaner and some form of compressed air to help you clean the small components.
Ensure that your vehicle’s engine is cool and the negative battery terminal is disconnected before removing the carb. Then, label all the different hoses and connections. This will help you be sure that you’re replacing them correctly when the time comes to put the carb back in. It can also be helpful to snap a photo with your smart device that you can refer to later. Then, you can disconnect the fuel line, watch for any fuel that might leak out, and take off the linkage and any other connections. Once this is done, unbolt the carb from the manifold and carefully lift it out. Put a clean show towel over the opening to the intake manifold to prevent anything from falling inside, which will cause engine damage.
Place the carburetor on a clean workbench or flat surface sitting on something that will fit underneath it so that it can sit level with the linkage hanging below on the side. First, loosen the two torx screws at the top in the center and rotate the covers so that the metering rods, plungers, and step up springs can be removed. Next check around the top cover and disconnect and linkage that will be in the way of removal such as the accelerator pump connection. Once clear, remove the top cover with a #15 torx bit or driver. Once the cover is removed, you can organize the internal components like the floats, jets, and metering rods. Also remove the idle mixture screws from the front of the carburetor. You can then start to clean an Edelbrock carburetor when everything is disassembled.
How To Clean An Edelbrock Carburetor
Using a brush, scrape away any deposits or grime that have built up on the parts, including the top cover and the assembly itself. Look for any passages or holes and spray them with carburetor cleaner to ensure they are free-flowing and don’t have any blockages. Use compressed air to blow through these holes and passages and ensure any deposits or buildup have been completely removed.
Place any smaller parts, except gaskets, rubber, or plastic components, in a container of carburetor cleaner and scrub them with a brush after thoroughly soaking them.
How To Clean Edelbrock Carburetor Jets
Carburetor jets, in conjunction with the metering rods, control the fuel flow into the carb and ensure the right air-fuel mixture is achieved. If your carburetor jets become dirty or clogged, you won’t get the proper fuel in the mix, and your engine will run lean. This can cause a variety of issues, like stalling or poor acceleration. Knowing how to clean Edelbrock carburetor jets and the carb itself will help keep your engine running smoothly.
Once you have removed the jets from the assembly, soak them in a container of carburetor cleaner for at least an hour. Afterward, use a thin wire or a specialized carburetor jet cleaning brush to clean the jet orifices. This tool should be thin enough that it doesn’t make the hole any bigger but big enough to remove any deposits thoroughly. Spray more carb cleaner into the jets to ensure the passages are clear. Afterward, you can clean the jets externally and reassemble the entire carburetor for reinstallation.
Tips For Protecting Your Carburetor
Along with a good cleaning, there are other things you can do to ensure that your Edelbrock carb stays in great shape for the long haul. The best thing you can do is use high-quality fuel from a gas station. Dirty, contaminated fuel can cause many issues with your engine, but it can be challenging on your carburetor. If possible, avoid using any ethanol-blended fuels, as ethanol will absorb more moisture and cause deposits and condensation within the carburetor assembly. Using fuel system cleaner additive in your gas tank every 12,000 to 15,000 miles is also helpful in maintaining a clean path for fuel.
In addition to ensuring your carburetor is getting the cleanest fuel, you also want to be sure that the air coming in is as clean as possible. Be vigilant about replacing your engine air filter once every 12,000 to 15,000 miles, or sooner if it’s dirty. A dirty or clogged air filter will allow debris and dust into the carburetor. When this mixes with fuel, it will quickly turn into deposits that can restrict the flow of fuel and air. The cleaner the air and fuel that comes into the carburetor, the better engine performance will be.
