On average, an automotive carburetor replacement costs $200 to $600. Depending on the make and model of your vehicle, parts can cost $100 to $300, with additional labor costs of $100 to $300.

Keep in mind: Carburetor (carb) repair costs vary also depending on whether you’re installing a high-end performance or fuel efficiency carburetor. For example, performance carburetors range between $150-$1,000 for parts alone.

How long does it take to replace a carburetor? Carburetors can take up to 3 hours to replace, although it could take shorter or longer depending on your vehicle's make and model. Times can vary as a result of what car repairs need completed. Smaller jobs, such as tightening adjustment screws, repairing fuel lines, and cable management can be done quicker than larger jobs, like replacing and installing a new carburetor.

What parts do I need for my carburetor replacement and how much do those parts cost?

To perform a carburetor replacement, you will need either an aftermarket or rebuilt carburetor:

Aftermarket or rebuilt carburetor: The carburetor is a component on older vehicles that atomizes fuel and mixes it with air. Depending on the style of carburetor you choose, a new aftermarket carburetor could cost anywhere from $500 to $2,000. A rebuilt carburetor is a much cheaper option at $200 to $500, but it won’t be as efficient, and it won’t last as long.

You may also find that you can rebuild your own carburetor using one or more of the following parts:

Float chamber: In a carburetor, the float chamber acts as a sort of storage fuel tank, thus allowing it to continuously supply fuel to your vehicle. Each float chamber has a float valve that works to maintain the fuel levels in the chamber. The average float chamber costs $15-$30.

Strainer: The strainer filters the fuel before it enters the float chamber. It’s made up of a fine wire mesh that removes dust and other debris from the fuel. Without it, blockage can occur in the nozzle, interrupting flow. Strainers typically cost upwards of $50.

Metering system: Metering systems are responsible for correcting the mixture of air-fuel by controlling the flow of the fuel into the nozzle. As air passes through the venturi, it creates a low-pressure field to aid in comparing pressure in the float chamber. From there, fuel is put into the air stream to the metering orifice. A new metering system will run you anywhere from $60-$100.

Idling system: For instances where you’re at idle speeds, the idling system allows for rich mixtures of air and fuel to pass from the float chamber to the venturi tube. Idling systems generally cost between {X} and {X}.

Throttle valve: At the exit of the venturi tube, a butterfly valve is placed to control the speed of your vehicle by supplying a specific amount of air-fuel mixture. If open, more mixture is pulled into the cylinder giving a higher output. Less mixture means less power. These parts can vary in price, costing around $7-$80 depending on the type you select.

Choke valve: Similar to the throttle valve in construction, the choke valve is located at the entrance of the venturi tube. It supplies a very rich mixture of air-fuel during the beginning of the colder seasons. If fully open, a normal amount of air can flow through the venturi, forming a normal mixture. If closed, a lower amount of air but higher amount of fuel passes through the discharge nozzle giving a richer combination. Parts typically cost between $5-$50.

Many of these parts can be found together in carburetor rebuild kits that usually sell for anywhere from $15 to $50 depending on the parts included. You can buy carburetor parts for your vehicle from auto parts stores such as AutoZone, Advance Auto Parts, and O'Reilly Auto Parts, or from online retailers like Amazon and Summit Racing. Our top three recommended brands for carburetor parts are Holley, Edelbrock, and Weber, but keep in mind that prices and recommended brands will vary depending on your vehicle’s year, make, and model.

Should I buy OEM or aftermarket parts?

When shopping for your carburetor replacement, either OEM or aftermarket parts are acceptable. As OEM products are designed to fit your vehicle, and most carburetors vary in size depending on your vehicle, this is definitely the safest option. However, if you’re searching for budget-friendly options with the same quality, aftermarket products are most likely a better fit.

Where can I buy parts for my carburetor replacement?

Most carburetor replacement parts and kits can be purchased online and in-store at various auto body and repair service shops, like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts. Additionally, carburetor kits and parts can also be found across online retailers, including Amazon and Summit Racing. Refer to your owner’s manual before purchasing to ensure you’ve selected the right parts and sizes for your vehicle.

How will a mechanic replace my carburetor?

As there are several different types of carburetors for various vehicle makes and models, your mechanic’s step-by-step process may vary. However, most mechanics will follow this process to complete your carburetor repair:

Inspection: Before beginning, your mechanic will examine your vehicle and engine code to determine whether or not more damage has occurred.

Disconnect battery cables: After confirming that you require a carburetor replacement, your mechanic will disconnect your battery cables to avoid any sparks that could occur. Since removing a carburetor requires direct contact with gasoline, this is an important step to prevent potential fires.

Remove air filter/fuel filter: As most carburetors have an air filter or fuel filter to keep debris out of the engine, it will need to be removed by unscrewing any bolts, clips or screws.

Identify and remove vacuum hoses: Next, your mechanic will identify and remove vacuum hoses and other connections, like the pressure control solenoid. They may also take photos of the hoses prior to removal to refer to when re-installing.

Remove linkages: If your vehicle has throttle linkages, these will also be removed as they are attached directly to the side of the carburetor.

Disconnect fuel supply line: Once the fuel supply line is disconnected, your mechanic will release any residual fuel pressure in the line.

Remove old carburetor: Finally, the old carburetor is removed by undoing any bolts, nuts, studs, and screws holding it in place. When removing the carburetor, your mechanic will use extra caution as too much force can damage or break the flanges, which will cause vacuum leaks and rough running conditions.

Block off intake manifold opening: To prevent debris build up in between steps, your mechanic will block off the intake manifold opening.

Install replacement: Before the installation of your new carburetor, your mechanic needs to perform a carburetor cleaning to ensure all debris and dust is clear for a leak free seal. If a new gasket is required, your mechanic will remove the old one and then apply a new gasket before placing it in the new carburetor. If necessary, your mechanic will also apply a new fuel filter.

Check for leaks: When all the steps are completed in reverse order and your new carburetor is in place and secure, your mechanic will check for leaks by starting the vehicle and listening for whistling noises.

Final inspection: Once all the above are finished, you will most likely conduct a road test to ensure proper functioning. If a fuel smell is detected during this time, pull to the side of the road and shut the engine off immediately and contact your mechanic.

What happens if I don’t replace my carburetor?

Carburetors are the mainframe for your vehicle’s fuel. If you don’t replace your carburetor or perform regular maintenance on it, build up is likely to occur and cause further malfunctioning. The following are results of a neglected carburetor:

Decreased fuel efficiency (more gas stops)

Engine damage and failure

Poor engine code readings

Poor air/fuel flow

Transmission issues

Defective control circuit (float, choke, idle, etc.)

What is a carburetor?

A carburetor is used to mix both air and fuel together to help your engine cylinders to power your vehicle. It operates using vacuum power and cable control and is classified as the ‘heart of the engine’.

Although carburetors aren’t often used in modern vehicles, they can be found in older models and makes. There are currently 3 kinds of carburetors on the market: the single barrel, double barrel, and quad carburetors, which possess up to 4 venturis to provide more power. Each type of carburetor also includes a variety of sub-types.

When should I replace the carburetor on my car?

Carburetors should be replaced every 100,000 miles, but routinely inspected for cleaning purposes. A dirty carburetor can cause just as many problems and as much damage to your vehicle’s internal systems as a defective one.

Common symptoms of a deteriorating carburetor are:

Reduced engine performance: This is the biggest sign that your carburetor either needs cleaned, or replaced. The carburetor manages air and fuel mixtures to help you get the best performance out of your vehicle. If it’s not getting the same gas mileage or is slow to accelerate, check your carburetor.

Black exhaust smoke: No black exhaust smoke should ever come from your exhaust pipe, even in diesel vehicles. This indicates that there is too much fuel in the mixture, and too rich of a mixture burns additional fuel and emits increased emissions.

Backfiring/overheating engine: If your fuel mixture is too lean due to a faulty carburetor, your engine can backfire or overheat, affecting your car’s performance.

Difficulty starting: When the air-fuel mixture in your car is off, you may experience trouble starting it due to poor fuel economy. While this could be a sign of a damaged battery or starter, it’s also worth checking your carburetor.

How often should a carburetor be replaced?

Carburetors only need to be replaced every 100,000 miles, depending on the make and model of your vehicle. If you have an older model vehicle, then it’s possible that it may need to be replaced more frequently. However, carburetors do require regular maintenance and cleaning, as a buildup of gunk can clog the internal systems and cause further damage.

Can I replace my carburetor myself?

Yes, but only do so if you’re confident in your DIY abilities and mechanical knowledge. While carburetor replacements are one of the more simple car repair processes, it also requires an understanding of battery cables, fuel systems, and auto parts. If you’re unsure of which steps to take, contact a licensed mechanic to assist in replacing your carburetor.

Warning: Fuel is extremely flammable, so when completing a carburetor replacement on your own, make sure to take extra precautions to prevent injury and increase your overall safety.

FAQs

Are carburetors hard to maintain?

No, with proper care and maintenance, carburetors aren’t difficult to maintain. However, if you need a carburetor replacement, this is where things can get expensive. If you suspect you need a carburetor replacement, it’s best to contact a mechanic who can inspect your engine code and determine exact pricing.

Does the carburetor affect speed?

Carburetors affect fuel consumption, acceleration, and high speed driving. When your carburetor is faulty, it can impact your vehicle’s overall performance, causing sluggish acceleration.

What replaced the carburetor?

Fuel injection is the main reason why carburetors were phased out from modern vehicles and replaced with electronic fuel injection systems. Fuel injection is easier to control and uses fuel more efficiently, resulting in lower fuel consumption and emissions.
