Classic cars with carbureted engines are cherished for their simplicity and nostalgic appeal. However, owning a carburetor-equipped vehicle comes with its own set of challenges. At Thoroughbred Performance and Engineering, we specialise in maintaining, repairing and modifying classic carburetor cars. In this blog post, we'll explore some of the most common issues faced by classic carburetor car owners and provide expert tips on how to fix them.
Common Issues with Classic Carburetor Cars
1. Hard Starting
One of the most frequent complaints from classic car owners is hard starting, especially in cold weather. This issue is often caused by improper choke adjustment or a faulty choke mechanism.
2. Rough Idling
A rough idle can be a sign of several problems, including vacuum leaks, dirty carburetor jets, or incorrect air-fuel mixture.
3. Poor Fuel Economy
Classic carburetor cars are known for their charm, not their fuel efficiency. However, excessively poor fuel economy can indicate issues such as a stuck float or a malfunctioning needle valve.
4. Hesitation or Stumbling on Acceleration
Hesitation or stumbling when accelerating can be caused by a lean fuel mixture, clogged accelerator pump, or ignition timing issues.
5. Black Smoke from the Exhaust
Black smoke from the exhaust usually indicates a rich fuel mixture, meaning too much fuel is entering the combustion chamber.
