How To Choose The Best Carburetor

Carb Size

To get the best performance out of your engine, you will need a carburetor that is matching and compatible.
Don’t be tempted to buy a big sized carb thinking that it will generate more power! Your engine might burn out and suffer from poor gas mileages if it receives more fuel than necessary.

The Society Of Automotive Engineers has established a CFM (Cubic Feet Per Minute) formula to help you find the right size of carb for your engine.

The formula for how much CFM your engine needs is:
Carb CFM = engine size (cubic inches) x Maximum RPM/3456

Here, the formula assumes that your engine has 100 percent volumetric efficiency. Most of the vehicles are only capable of getting 80 percent efficiency in real life.

For example, if the engine size is 400 cubic inches and the maximum RPM is 6000, then the engine would require 694.44 CFM (400 x (6000/3456)). In this case, you will need to choose the closest available size of the carburetor, which is 700 CFM.

RPM Range

RPM stands for Rotation Per Minute. When a vehicle is stopped at a red light and the engine keeps running, its idle speed is measured by the RPM. The engine still generates power, but it’s incapable of generating any movement at that time.

Before you start choosing a carb, know about your engine’s RPM range capacity. Depending on the minimum and maximum RPM, you can decide which carburetor your car needs.


You can choose a carburetor with or without a choke element.

If you live in a warm climate, then you may ignore this one. However, in a cold region, your engine most likely won’t start without a choke.

When the temperature of an engine gets low, it requires a richer air and fuel mixture to start. The choke, covering the primary barrels of the carb, restricts the air that passes through. Thus, it fills the carburetor with more fuel and warms up the engine to start.

You can choose from 2 types of choke available on the market. Manual or Automatic.

If you choose a manual choke for your carburetor, you will need to operate it by hand. On the other hand, an automatic choke doesn’t need any physical assistance. As the engine starts to get hot the automatic choke opens its valves by itself.


Make sure your carb has a good throttle response. When you put pressure on the accelerator paddle, a throttle valve opens and controls the airflow to the carburetor.

Carb in a good condition results in a quick response to the acceleration request. Your engine’s durability and performance depend upon the quality of the throttle you choose for its engine.


A good quality carburetor tunes easily with your vehicle. To make sure of that, always make sure you’re purchasing the right carb for your car model.

You should check to see if all the features are easily adjustable. Depending on your preference, you can choose to have an adjustable air filter, choke, screws, etc.

Frequently Asked Questions

1. What Makes A Carb Overflow?

Answer: Carburetor overflow occurs in two situations. The float needle valve may get stuck or worn out over time. As a result, the valves can’t close properly causing fuel to overflow into the ball. Ethanol contained fuel can also cause overflow by damaging the carburetor.

2. How Can I Connect An Electric Choke?

Answer: You have to connect only two wires to the voltage source. First, take the red wire, which is the positive voltage wire. Then make a connection between a switched 12-volt ignition source and the positive wire. Add the black wire to ground to complete the process.

3. How Do I Know If My Carb Is Failing?

Answer: If you experience a slow performance from your engine, it might be an indication of a carburetor failing. You will notice your engine struggling with acceleration and consuming more fuel than necessary at times. Black smoke coming from your engine is also a symptom of a carb failing.

4. Is A Vacuum Secondary Carb Is Better Than A Mechanical One?

Answer: Not necessarily. It depends on what type of car you are driving. If you own a street car with automatic transmission, then a vacuum secondary carb is the best option for you. A mechanical carb is mostly suitable for racing cars.

5. Why Does My Engine Run Rough When Cold?

Answer: When the temperature starts to drop, the engine needs more fuel to run. The choke in your engine is responsible for warming it up. Chokes get easily displaced. Check to see if it’s closing properly and replace if it gets defected over time.

Final Words
Whether you are driving through the streets casually or preparing to take part in a stunt racing, your car relies on its engine the most. Your vehicle isn’t going anywhere if the engine fails for some reason.

So what makes an engine perform at its best? An engine runs smoothly only if it’s properly tuned. A good carburetor can adjust properly with your engine and ensures a top-notch performance from your car.

Hopefully, this article will help to choose the best carburetor for your engine depending on your vehicle type, model, RPM range and preference.
