How to Buy a Good Quality Carburetor

Vehicles are now manufactured using a fuel injection system in order to provide the engine with the proper fuel-air mixture. Prior to the 1980s, however, carburetors performed this task. The carburetor is similar to a throttle body in that it contains a pipe and a valve, however a carburetor doesn’t use any electronic mechanisms like a fuel injection system does. Rather it uses the Venturi principle of vacuum creation to allow just the right amount of fuel through a needle valve inside the unit and out to the engine.

At some point the carburetor may become warped, cracked, or otherwise malfunction, and will need to be replaced. People also sometimes upgrade the carburetor for performance purposes.

How to tell if your carburetor is bad

  • Hard starts – you may need to hold the key in the start position for several seconds
  • Roaring, vibrating, or rough running when idling
  • Decreased fuel economy
  • Stalling or rough running while driving
  • Leaking fuel

This combination of signs doesn’t necessarily mean that the carburetor is bad, but you should have it inspected by a mechanic if you’re experiencing these problems.

Once it has been determined that you need a new carburetor, you’ll need to decide between buying a rebuilt or new one. Carburetors can be remanufactured but it’s critical that you know whom you’re buying from. You must also inspect the part yourself first, and keep in mind that internal damage is difficult to detect.

How to make sure you’re getting a good quality carburetor

  • Choose a carburetor with good throttle response. Throttle response is measured by how quickly the engine responds to acceleration requests. When you push your right foot to the floor, you should get a quick response by the engine with minimal lag time. When flooring the gas pedal, it should take less than a second for the tachometer to hit redline. As a standard measure, a carburetor with a CFM (cubic feet per minute) between 500 and 750 should perform well for all of your typical driving situations. Having good throttle response improves your car's performance and maximizes your engine’s potential.

  • Check the warranty. Particularly if buying a rebuilt carburetor, you want to make sure that the part is guaranteed should something go wrong. Whether buying a new or rebuilt carburetor, you should make sure that your warranty has you covered for up to 100,000 miles.

  • Buy a carburetor that is easy to tune. This means that all adjustment features, including screws and air filters, are easily accessible in the case that you'd like to adjust the idle air/fuel mixture to your preference.

Keep in mind that carburetors may pose an issue with passing emissions tests required by some states. You want to check your local laws to make sure that the part you’re installing is legal and that your car will still be able to pass the necessary smog testing.

Ford Fusion - 75 Point Safety Inspection - San Jose, California
I have ordered a 75-point inspection of the car since my dealership claimed it had an oil leak and the timing cover replacement was due (this kind of repair costs in the ballpark of a thousand dollars). I mentioned the need for a second opinion on that since the car had been bought relatively recently from that dealer (certified pre-owned) and not very actively used. Pradeep performed the safety inspection in a very timely manner and addressed my main question by honestly concluding that there was no leak but just some dust collected over time. This has saved me much time and money. Finally, I was also very glad to learn a tip on how to find a matching paint for a body scratch from him.
Ford Escape - 75 Point Safety Inspection - San Jose, California
Pradeep immediately found the suspension problem I was worried about and fixed it. We had just purchased this car and now feel a lot better about it now that he has checked it out.

Honorio went above and beyond my expectations. He was honest about which repairs needed to be done even though my service revision decreased his income. Will absolutely use again!!!! Thank you!
