Honda Civic Carburetor: Common Problems and How to Solve Them

If there's one part that your vehicle can't function without, it's the carburetor. Without it, the engine will not work because it will not receive the right mixture of air and fuel. However, due to various factors, the carburetor eventually gets damaged. Listed below are some of the common problems that you may encounter with your Honda Civic carburetor.

Poor fuel economy

If you are experiencing sudden dips in your Honda Civic's fuel economy, then you have to check the carburetor for damages. Usually, because the power valve of the carburetor is damaged, the engine no longer receives the right amount of fuel it needs to function properly, therefore compromising fuel economy. To solve this problem, repair your carburetor's power valve immediately once it becomes faulty.

Dark exhaust smoke

Another sign that your Honda Civic carburetor is about to go out is seeing dark exhaust smoke coming from the tail pipe. Although this can also be attributed to a faulty exhaust system component, seeing black exhaust smoke is more often than not the result of a carburetor problem. This happens because the engine no longer receives the right ratio of air and fuel mixture from the carburetor. As a solution, you can either replace the damaged carburetor with a new one, or rebuild the faulty one using a carburetor rebuild kit.

Misfiring engine

If your Civic's engine is misfiring, then you need to check the carburetor as soon as possible. Usually, a damaged carburetor restricts the flow of air and fuel in the cylinders of the engine. As a result, misfires occur because the combustion process in the engine is compromised. You can solve this problem by rebuilding your Civic's damaged carburetor. However, make sure that you are going to purchase a rebuild kit because it contains all the parts that you will need to successfully do the task.

Fuel leaks

In order to prevent fuel from leaking into the engine, the carburetor is equipped with a gasket that is typically made from high-grade rubber. However, due to constant exposure to varying temperatures, this gasket eventually gets cracked or corroded. When this happens, your Civic will become a safety hazard because there is a possibility that the fuel might suddenly ignite. To prevent fuel leaks, always inspect the rubber gasket for signs of damage. In case it is already corroded, just purchase a replacement gasket, and install it at home.

  • Ways to Keep Your Honda Civic Carburetor in Good Shape

    The carburetor installed in your Honda Civic is an indispensable part because it plays an important role in the combustion process. Without it, the engine will not receive the right air and fuel mixture that it needs to generate power. Unfortunately, just like other car parts, the carburetor will also cause problems if it is not taken care of properly. Check out the list below for some tips on how to keep this part in peak condition:


    Clean the carburetor routinely.


    One way to make sure that the carburetor of your Honda Civic will work properly is by cleaning it every 3,000 miles or so. Fortunately, this process can be done at home, and it will not take more than 30 minutes. However, if you will clean the carburetor yourself, make sure that you will use a choke and carburetor cleaner that can be purchased from a car parts store. Also, if you will use a lubricant, make sure that you will only spray it on the outside areas to avoid damaging the carburetor.


    Rebuild your carburetor when necessary.


    If your Honda Civic carburetor is already failing, but you do not want to purchase a replacement, then you can have it rebuilt instead. Although rebuilding a carburetor requires much work, it is still a good idea because you can save a lot of money. You only need to purchase a rebuild kit to make this part function like its new again. However, make sure that the kit you will purchase is designed to fit your vehicle's make and model.


    Make sure that the idle-mixture screws of the carburetor are adjusted properly.


    An improperly adjusted carburetor is one of the most common culprits behind poor idling. So, after cleaning or rebuilding this part, make sure that the idle-mixture screws are at their initial setting. Also, don't forget to adjust the transfer slots because if they are exposed, the screws will not be able to control engine idle properly.


    Inspect the carburetor for leaks regularly.


    Due to constant exposure to varying temperatures, your Honda Civic carburetor may leak fuel due to a damaged rubber gasket. Once this happens, your vehicle will become a fire hazard because the fuel can ignite anytime. To avoid this, always inspect the carburetor for leaks before taking your Civic for a drive. If it is leaking, replace the rubber gasket immediately.
