Carburetor Adjustment: How to Know When You Need to Have One Done

Carburetor Adjustment: How to Know When You Need to Have One Done

If you own a vehicle that’s on the newer side, there is a good chance that it doesn’t have a carburetor in it. Back in the 1980s, many car manufacturers started to introduce fuel injection and electronic engine control systems into their vehicles, and it eliminated the need for carburetors. But if you own a vehicle that’s on the older side, then you could very well have a carburetor in it. And it’s going to be important for your carburetor to be working properly at all times for the good of your engine. This might require you to schedule a carburetor adjustment every so often. Learn more about the importance of carburetors and see some of the signs that’ll show you it’s time to do a carburetor adjustment below.

What Is a Carburetor?

In order for your car’s engine to work the way it should, it needs to get access to both air and fuel. This is what allows for the combustion process to play out in your engine so that it can provide your car with the power that it needs to move forward. But more specifically, your engine needs the right blend of air and fuel. If it gets too much air or too much fuel, it can cause complications within your engine. This is where a carburetor comes into play.

 

When a car has a carburetor in it, the carburetor is responsible for regulating the air-fuel mixture that is sent to the engine. As a result, the carburetor in a car needs to be working in the right way so that it can send the proper amount of air and fuel to the engine. If it’s not able to do this, you’re going to have to either perform a carburetor adjustment or replace a carburetor altogether. Either way, it’s going to be important for you to take the right steps to get your carburetor working properly again.

How Does a Carburetor Work?

Now that you have a basic understanding of what exactly a carburetor does within the context of your car, let’s talk a little bit more about how one works. It’ll help to shed some light on why you’re going to need to do either a carburetor adjustment or a carburetor replacement at some point in time. Carburetors are fairly complicated devices that need to be tinkered with from time to time to ensure that they’re able to carry out their jobs.

 

The carburetor in your car is essentially a metering valve that is designed to mix together the air and fuel that are moving in the direction of your engine at all times when your car is running. It works in tandem with your gas pedal to combine the right amounts of air and fuel as you seek to speed your car up or slow it down. When you push down on the gas pedal, you’ll increase the amount of air passing through your carburetor and pulling fuel along with it, which will result in your car going faster. And when you take your foot off the gas pedal, you’ll decrease the amount of air passing through your carburetor and prevent fuel from moving through it, which will result in your car going slower.

 

With these things in mind, it’s easy to see why it’s so essential for your carburetor to be in good condition at all times. If one of the parts in it stops working or if it gets clogged up at any time, it can really drag down the performance of your car. You’ll need to have a carburetor adjustment done or replace your carburetor to bring it back to life and allow it to start doing its job again.

How Long Should a Carburetor Last?

The good news for those who have carburetors in their vehicles is that they’re usually not going to wear out in just a year or two. You’re going to be able to get a lot of life out of a carburetor. You might even get lucky and be able to continue using the same carburetor in your car for the life of it. But to make this possible, you will have to work to maintain the carburetor in your vehicle.

 

One of the best ways to maintain your carburetor is by having a carburetor adjustment done every now and then. You can prevent your car from “running lean” (using too much air and not enough fuel) or “running rich” (using too much fuel and not enough air) by adjusting your carburetor accordingly. You will still probably have to replace your carburetor down the line at some point. But adjusting it is a fantastic way to breathe life back into your carburetor and keep it humming along.

What Are the Symptoms of a Bad Carburetor?

So, how will you know if and when your car’s carburetor needs to be adjusted or potentially even replaced? It’ll actually be fairly easy to spot the signs that’ll show you that you need to have work done on your car’s carburetor. You’re going to notice that your car doesn’t seem to be running the way it should when you have a bad carburetor on your hands.

 

Check out some of the biggest symptoms of a bad carburetor here:

  • Your car is always very hard to start, especially when it’s cold outside
  • Your car doesn’t idle smoothly as you experience either rough or fast idling on a regular basis
  • Your engine stalls out on you all the time when you don’t have your foot on the gas pedal
  • Your car tends to hesitate before accelerating whenever you push down on your gas pedal
  • Your engine sends black smoke shooting out of your exhaust all the time
  • Your car has terrible fuel economy and always seems to be in need of gas

Each of these signs could, of course, be a sign of another problem with your car. There are all kinds of things that can have an impact on something like fuel economy. But if you see more than one of these signs, it could mean that you need to have a carburetor adjustment or carburetor replacement done right away. Otherwise, your car’s performance is going to continue to suffer for the foreseeable future.

What Should You Do If You Have a Bad Carburetor?

If you believe that you might have a bad carburetor, you should not continue to drive your car all over town. You’re going to put your car and possibly even yourself at risk if you push a car with a bad carburetor beyond its limits. A bad carburetor could cause damage to your engine and your exhaust system if you’re not careful. It could also put you into dangerous spots if your car stops accelerating because of your bad carburetor.

 

Your best bet is going to be to take your car to an ASE-certified mechanic right away so that they can take a look at your car and see what seems to be the problem with it. They should be able to tell you whether or not you need to have your car’s carburetor replaced. If you do, you’re better off doing this as soon as you can so that you don’t hurt your car or yourself by driving around in a vehicle with a bad carburetor in it.

Is a Carburetor Adjustment an Option?

If you have a carburetor in your car that’s not working like it should, you might have no choice but to replace it. Your car’s carburetor isn’t going to last forever, so you’ll have to replace it one day. But you might also be able to get away with doing a simple carburetor adjustment to it. A carburetor adjustment will allow you to keep your current carburetor by making it work better than it’s working for you now.

 

These are the steps that will be taken when a mechanic performs a carburetor adjustment for you:

  • The air filter in your car’s engine will be removed
  • The air-fuel mixture will be adjusted through the use of a screwdriver
  • The engine’s condition will be observed to see if it’s “running lean” or “running rich”
  • The air-fuel mixture will be readjusted and the engine’s condition will be observed again
  • The idle mixture screw will be adjusted and then tested
  • The air filter will be reinstalled and the car will be test-driven

It might take a mechanic a little while, but they should eventually be able to fine-tune your car’s carburetor so that it achieves the perfect air-fuel mixture, both when you’re driving your car and when it’s idling. There is a science to conducting a carburetor adjustment and finding the sweet spot for a car’s engine.

Should You Attempt a Carburetor Adjustment Yourself?

After seeing the steps that are involved with a carburetor adjustment, you might be under the impression that you can perform one yourself. It doesn’t seem like it would be all that difficult to pull off a carburetor adjustment since you don’t really need anything other than a decent screwdriver set to pull one off.

 

But as we just alluded to, it often takes a lot of trial and error to conduct a successful carburetor adjustment. Mechanics have to tinker with the screws on a carburetor a lot to get things just right. It requires them to test and retest the carburetor in a car over and over again to get the best results. It’s not something that most people are cut out to do, even if they know their way around a car.

How Much Does a Carburetor Adjustment Cost?

If you ever need to replace the carburetor in your car, it’s going to cost you a pretty penny. The exact cost is going to depend on everything from what kind of carburetor you need to which mechanic you trust to put it into place for you. But generally speaking, you’re going to be looking at paying between $500 and $800 for it when everything is all said and done.

 

A carburetor adjustment, on the other hand, shouldn’t break the bank. You’re typically going to have to pay just a couple hundred dollars to have your carburetor adjusted, if not less than that. It’s not something that’s going to break the bank in most cases. You’ll just need to make sure you call on the right mechanic to get the job done.

Is the Carburetor Adjustment Cost Worth It?

Once you have a carburetor adjustment done, you’re going to find that it was well worth the costs associated with it. Outside of the fact that it’ll help you hang onto your car’s carburetor for a little bit longer, it’s also going to reduce the amount of money that you have to pay for gas every week. Additionally, it’s going to prevent you from having to do other costly car repairs both now and in the future. It’ll be a great investment for your car.

 

The only time when you might want to skip over doing a carburetor adjustment is when you have a really old car that’s on its last legs. Rather than shelling out money to try and restore your carburetor, you might want to consider getting rid of the car altogether. It might not be worth trying to keep your carburetor intact if your car has lots of other issues with it.
