What is a carburetor?
A carburetor is used to mix both air and fuel together to help your engine cylinders to power your vehicle. It operates using vacuum power and cable control and is classified as the ‘heart of the engine’.
Although carburetors aren’t often used in modern vehicles, they can be found in older models and makes. There are currently 3 kinds of carburetors on the market: the single barrel, double barrel, and quad carburetors, which possess up to 4 venturis to provide more power. Each type of carburetor also includes a variety of sub-types.
When should I replace the carburetor on my car?
Carburetors should be replaced every 100,000 miles, but routinely inspected for cleaning purposes. A dirty carburetor can cause just as many problems and as much damage to your vehicle’s internal systems as a defective one.
Common symptoms of a deteriorating carburetor are:
Reduced engine performance: This is the biggest sign that your carburetor either needs cleaned, or replaced. The carburetor manages air and fuel mixtures to help you get the best performance out of your vehicle. If it’s not getting the same gas mileage or is slow to accelerate, check your carburetor.
Black exhaust smoke: No black exhaust smoke should ever come from your exhaust pipe, even in diesel vehicles. This indicates that there is too much fuel in the mixture, and too rich of a mixture burns additional fuel and emits increased emissions.
Backfiring/overheating engine: If your fuel mixture is too lean due to a faulty carburetor, your engine can backfire or overheat, affecting your car’s performance.
Difficulty starting: When the air-fuel mixture in your car is off, you may experience trouble starting it due to poor fuel economy. While this could be a sign of a damaged battery or starter, it’s also worth checking your carburetor.
How often should a carburetor be replaced?
Carburetors only need to be replaced every 100,000 miles, depending on the make and model of your vehicle. If you have an older model vehicle, then it’s possible that it may need to be replaced more frequently. However, carburetors do require regular maintenance and cleaning, as a buildup of gunk can clog the internal systems and cause further damage.
Can I replace my carburetor myself?
Yes, but only do so if you’re confident in your DIY abilities and mechanical knowledge. While carburetor replacements are one of the more simple car repair processes, it also requires an understanding of battery cables, fuel systems, and auto parts. If you’re unsure of which steps to take, contact a licensed mechanic to assist in replacing your carburetor.
Warning: Fuel is extremely flammable, so when completing a carburetor replacement on your own, make sure to take extra precautions to prevent injury and increase your overall safety.
