How to clean a Carburetor?

The carburetor is the place where gasoline and air mix before the gas continues to move through the engine. Keeping your carburetor clean will help the engine work correctly, prevent corrosion of the parts, and also save you a lot of money on costly replacements. 

The best part is that cleaning your carburetor regularly can help maintain the vehicle maintain efficiency in engine power and gas mileage. 

It is often seen that the air intake dries out the gas present in the carburetor, causing the buildup of a sticky substance that sticks to the walls of the carburetor. This sticky substance builds up over time. 

If you don't use your car regularly, this can even cause the gasoline to thicken over time, lowering the ability of the smaller parts of the carburetor to move correctly. And when the carburetor is dirty, connections that are attached to the carburetor's choke plates and throttle become sticky. 

The carburetor can also start to give off a smell of turpentine or a chemical odor that is different from the normal smell of gasoline. This is a sure-shot indication that your carburetor is long overdue for a clean-up. 

One of the biggest questions that car owners sometimes face is whether they should clean the carburetor themselves or get it done professionally.  If you have the time and expertise, it is possible to clean your carburetor by yourself, a process referred to as carburetor rebuild.

A complete carburetor rebuild should begin with first checking your car's Owner's Manual before you do anything. You must follow the manufacturer's instructions for cleaning and maintenance of the carburetor. Also, ensure that the carburetor has cooled down before cleaning. 

Here are the steps to follow for cleaning a carburetor.

  1. In a large container, mix one part of a certified carburetor cleaner with three parts of water. 

  1. Before you start cleaning the carburetor, check the air filter to ensure that the air coming into the carburetor is clean and there is no blockage. A sure sign of this is black smoke coming out of the exhaust. Close off the fuel supply and disconnect the wire of the spark plug. 

Now remove the housing and the wing nut that attaches to the filter. Also, remove the outer element. You can use a simple can of compressed air to remove any debris. 

  1. Now, it is time to remove the carburetor. Remove all hoses and linkage using a screwdriver and pliers where needed. Remove any clamps or cover holding the carburetor in place. Also, remove the hose clamp that connects the carburetor to the fuel line. Now you can remove the carburetor.

  1. Use compressed air to remove any excess and visible dirt from the outside casing. If you are unfamiliar with this step, it is best to consult a professional like National Carburetors before you start. 

  1. Remove the bolt that holds the carburetor float or the bowl-shaped container you can see. Be careful not to spill any remaining gas inside the float at this stage. Remove the pin that the float moves on, and keep it aside safely. Full the float out of its casing. 

  1. Remove any other removable parts and make a note of their location and placement. 

  1. Soak and scrub all the parts, making sure to clean the tiny vents. You can do this by putting the carburetor float and other smaller parts in a large container with the cleaning solution and allowing all the parts to soak thoroughly. Using a brass brush for scrubbing the metal parts will help get them clean, while a stiff nylon brush can be used to scrub and clean the plastic components.

  1. Rinse out all the carburetor parts in clean water and let the components air dry thoroughly. For the small vents and holes, again, use a can of compressed air to remove any moisture. 

  1. Now, carefully reassemble and replace all the components of the carburetor and mount it back onto the engine. Re-attach all the clamps, hoses, and wires.
