If your carburetor is failing and a routine adjustment won’t solve the problem; it may be time to replace it altogether. This usually costs anywhere from $500 to $2,000, depending on the make and model of the car, and should be taken care of sooner rather than later.
Over time, carburetors need to get adjustments to maintain the right fuel mixture and keep the engine idling normally. But eventually, you’ll no longer be able to make these adjustments, and you’ll need to replace the carburetor altogether. You could alternatively have the carburetor rebuilt, sometimes (but not always) for less than replacing it.
Let’s take a closer look at that first option of getting a carburetor replacement in this guide presented by the car insurance shopping super app Jerry.
The exact cost varies between different Bmw models. For example, newer vehicle models are usually made with more expensive materials, so recent or high-end models will cost more, especially if your service requires a part replacement. Use the table below to estimate the cost for your own vehicle.

What is a carburetor replacement?

A carburetor replacement will typically cost anywhere from $500 to $2000, sometimes more or less depending on the make and model of the car, and whether you’re installing a performance carburetor or a fuel efficiency one.
By comparison, rebuilding a carburetor might cost only $200 to $500. But this isn’t always an option, and a rebuilt carburetor usually won’t be as efficient as a brand new aftermarket one. Either way, you’ll want to discuss these two options with your mechanic.
The carburetor is an engine component mounted on the intake manifold that atomizes fuel and mixes it with air. This fuel mixture is then internally combusted in your engine’s cylinders, producing power. So it goes without saying your carburetor is an important car part.
Over time, the carburetor will need some adjustments to maintain the proper idling performance and to keep the fuel mixture correct. But as the carburetor gets older, these adjustments essentially stop functioning as intended, and you’ll end up faced with one of two options: replace the carburetor, or have it rebuilt.
A carburetor hasn’t been installed on a new car sold in America since the early 1990s; carburetors started getting phased out in the ’80s, and fully went extinct with the advent of modern fuel injector systems. So if you’re having carburetor trouble, your car is older and needs special care!

How to perform a carburetor replacement

Your mechanic will go through the following steps during your carburetor replacement:
  • Disconnect the car’s battery
  • Remove the air filter
  • Remove the old carburetor
  • Install the new carburetor
  • Install a new fuel filter
  • Install a new air filter
  • Reconnect the car battery
  • Inspect the engine and the carburetor for leaks and see if any adjustments are necessary
  • road test the car to make sure everything is running smoothly

Do I need a carburetor replacement?

You can usually tell when a carburetor needs an adjustment as the engine will start acting up. You’ll feel the engine running rougher. It might stall or not even start at all. You might hear backfiring out of your exhaust. It’s also common to smell or see fuel leaking.
You’ll want to get your carburetor checked and adjusted regularly, or learn how to adjust it yourself (it’s pretty easy and only requires some easy-to-use and affordable tools).

How important is a carburetor replacement?

If your carburetor is failing and can’t be adjusted or rebuilt, your engine’s fuel mixture will be off-kilter. This can lead to any number of performance issues, and might even cause the engine to stall out, or not even turn over at all. You should try to get this serviced as soon as you’re able.
