You have to give your car a lot of TLC to keep it running like new. The best policy is to be proactive. Maintain your car before an issue gets out of hand.
Your car’s engine will often let you know when something is wrong. Does your car give you poor fuel economy? Does it have a rough idle, or does it idle too fast?
These are all signs of a bad carburetor. If your car’s carburetor is giving you problems, you might need to replace it. Replacing a carburetor might sound like a hard task, but it’s easier than you think.
Read this article to learn how to replace your carburetor with the best part.
What Does the Carburetor Do?
Most new cars don’t have a carburetor, but those that do, need to have a good one. A carburetor helps to keep a car’s engine running by mixing air and fuel. One that works well will help control the engine’s speed.
The carburetor is a pipe that’s found over the engine cylinders. You’ll find the air and fuel pipe that connect to it.
Outside air flows through the air pipe and then goes through an air filter. This filter removes debris. From there, the air goes to the carburetor.
The carburetor contains two valves. Both of them work to produce a perfect air-to-fuel ratio. In layman’s terms, the carburetor works to meter fuel with air to deliver the mix to the engine.
Issues With the Carburetor
Now you might be asking, “How will I know when I have to replace my car’s carburetor?” This is a question that your carburetor will answer for you once it starts giving problems.
Gas engines must have the right amount of air. This allows the fuel to burn. This is where the carburetor comes in.
A carburetor that doesn’t work well can damage the engine if it isn’t producing the right mix of fuel. It can also prevent a car from running.
If there’s too much fuel, the engine can flood. Too much fuel can also cause the engine to smoke as the car is running.
Other issues that can arise include stalling at low speeds. You don’t want to reach this point, but if you observe these issues, it’s time to take action.
Choosing the Right Carburetor
If your car’s carburetor is giving you issues, you’ll need to replace the carburetor. You might be thinking that you have to spend a lot of money to take your car to a mechanic. You might also be thinking about having to spend lots of money on parts.
There’s good news. You don’t have to break the bank to replace this part. You can do it yourself.
You can save lots of money by using this step-by-step guide. The first thing you must do is buy the right part and tools.
One of the best carburetors in the market is the Edelbrock 1406 model. You can’t go work with this brand and model.
It comes with an electric choke and satin finish. It’s built to give your car top performance.
Now that you know which carburetor to buy, you need to buy the tools you’ll need to replace this part. You’ll need a flashlight and pliers.
It’s also helpful to have a wrench set and screwdrivers. Have a couple of towels on hand. They’ll come in handy for fuel spills.
Disconnecting the Battery Cables
The first thing you must do in this process is to disconnect the battery cables. This will help to avoid any sparks.
Because this process involves coming in contact with gas, you want to prevent any sparks. You don’t want to suffer any burn injuries.
Make sure to secure the cables. It’s a good idea to cover the cable terminals. The last thing you want is for the cables to come in contact with the battery.
Remove the Air Cleaner
The next step is to remove the air cleaner. This part covers the air intake filter.
You might also find ductwork or hoses. Take these parts apart to access the carburetor. Set them aside so they don’t get in your way.
Take the Vacuum Hoses and Other Connections Out
Look around the carburetor to identify the hoses that connect to it. Remove them. Put them aside so that they don’t get in your way.
You might want to take pictures so you know where to reconnect them after. It might be a good idea to put masking tape around the end of the hoses. This tape can help you remember where each one goes.
Removing Linkages and Disconnecting the Fuel Supply Line
After you remove all the hoses, it’s time to remove any linkages. Look for the throttle linkage. You’ll find it on the side of the carburetor.
You have to remove any linkage to separate the carburetor from the intake manifold. Put them to the side with the rest of the other carburetor parts.
Now it’s time to disconnect the fuel supply line. It might be in the form of a hose or metal tube.
You’ll need to see if there’s any fuel pressure left in the fuel line. If there is, make sure to release the residual pressure. Have the towels ready to catch the fuel that escapes.
Remove the fuel supply now. There might still be fuel in there, so don’t put away those towels yet. Once you’re done collecting residual fuel, you can put the fuel supply line off to the side.
Now separate the carburetor from the intake manifold. Do this by lifting it free from the intake manifold.
You might get some resistance as you attempt to do this. If you get any, you can use a screwdriver to pry it free. Do this with care as its parts are fragile and force can damage it.
The next step is to remove the old gasket if there’s one. You’ll find this part between the carburetor and intake manifold.
Prepare to Install the Replacement Carburetor
It’s now time to put in the replacement carburetor. Before you do this, you have to clean the replacement carburetor and the intake manifold. Use a light solvent for this.
If you need to install a new gasket do so. Most replacement carburetors come with a new gasket.
This is where the pictures you took will come in handy. Use the pictures to compare the placement of the old carburetor to the new one. Pay close attention to the features and linkages.
If all the parts are in the same position, you can then move the parts from the old carburetor to the new one. Don’t forget to take out any towels or tape you left in place.
Set the replacement carburetor in the intake manifold. You’ll have to connect the vacuum hoses and the fuel line. Next, you have to reinstall the linkage.
Check for Leaks
Next on the list is to check for leaks in the system. Inspect all the areas for any signs of fuel leakage. It’s a good idea to listen for a whistling sound as it can signal a vacuum leak.
If you find any leaks, you must shut off the engine. Be mindful not to cause any sparks. Take the time to clean up any fuel spills.
After cleaning up, you can repair the leaks. You can seal the leaks by tightening the fasteners. Once you do this, you can restart the engine.
Completing the Carburetor Installation
This is the home stretch. Remember all those parts you put to the side? It’s time to put these back into their places.
You’ll need to inspect the area. Do a visual inspection to see if you left any tools behind. Remove any foreign objects away from the area.
You can now test drive the car. Do this to make sure there aren’t any issues. If there are any issues, pull off to the side of the road and turn off the engine. Make any necessary repairs.
