Why Upgrade Your Carburetor?

1. Old or Faulty Carburetor

  • Common issues: Stuck floats, clogged jets, fuel delivery problems
  • Effects: Hard starting, rough idle, poor acceleration
  • Risk: Leaks from worn gaskets & seals

2. More Power & Throttle Response

  • Stock carbs are fuel-efficient but restrictive
  • Upgrade to: Larger CFM (e.g., 750 CFM 4-barrel) for better airflow & performance

3. Engine Mods Demand More Fuel

  • Needed if you have: High-flow intake, aggressive cam, open exhaust, or bigger bore
  • Solution: Higher CFM carb to match increased air intake

4. Easier Tuning for DIY Users

  • Simple adjustments: Idle screws, jets, float height (no ECU needed)
  • Best for: Vintage cars, track builds, or hands-on enthusiasts

5. Better for Special Conditions

  • Preferred in: Racing, off-road, tractors
  • Advantages: No electronics, reliable in cold/altitude/extreme environments

Upgrade Tip: Match your carb (CFM size...) to your engine’s needs!

FAQs about Carburetor

What is a Carburetor in a Car?

A carburetor is a mechanical device in older internal combustion engines that mixes air and fuel in the correct ratio for combustion. Located between the air filter and the intake manifold, it uses engine vacuum and fuel jets to atomize fuel and deliver it to the cylinders.

The primary function of a carburetor is to:

  • Mix air and gasoline in the ideal ratio (usually around 14.7:1 for gasoline engines)
  • Control engine speed and throttle response
  • Provide extra fuel when accelerating (via an accelerator pump)
  • Maintain stable idle and efficient fuel delivery at all RPM ranges

It essentially manages how much fuel your engine gets at any given moment, depending on throttle position and engine load.

Choosing the best carburetor depends on your engine type, driving style, and performance goals. Consider the following factors:

  1. Engine Displacement
  2. CFM Rating (Cubic Feet per Minute)
  3. Barrel Type
  4. Choke Type
  5. Application Type
  6. Brand and Compatibility

For example, if you own a small-block V8 and want a balance of performance and driveability, a 600 CFM square-bore carburetor with vacuum secondaries would be ideal.

No, most modern vehicles do not have carburetors. Since the late 1980s to early 2000s, automakers transitioned to electronic fuel injection (EFI) systems, which are more efficient and environmentally friendly. Today, carburetors are mainly found in:

  • Classic cars
  • Some off-road or motorsport vehicles
  • Small engines (like motorcycles, lawn mowers)

No, a car with a carbureted engine cannot run without a carburetor, as it would have no way to mix and deliver fuel to the engine. However, carbureted cars can be converted to EFI, which replaces the carburetor with a fuel injection system. EFI systems are more efficient, especially in cold starts and altitude changes.
