For classic car enthusiasts, preserving the pristine condition and optimal performance of their cherished vehicles is a constant battle. Amidst the array of maintenance tasks, one crucial aspect often overlooked is the carburetor. This unassuming component plays a pivotal role in fuel delivery and engine operation. Neglecting its cleanliness can lead to a cascade of issues, ranging from rough idling and sluggish acceleration to complete engine failure. Cleaning the carburetor on your classic car regularly or after storage can avoid all the hassle and drama.
In essence, the carburetor is responsible for mixing air and fuel in the precise ratio required for combustion. Over time, however, the carburetor’s intricate passages and jets can become clogged with dirt, grime, varnish, and residue from fuel additives. This buildup disrupts the delicate balance of the air-fuel mixture, leading to a host of performance problems and potentially causing irreversible damage to the engine.

Carburetor cleaning on a classic car is not a task for the faint of heart anymore. It demands specialized knowledge, diagrams, meticulous attention to detail, and the right tools. In the days past, most shops were well equipped to handle this task, because most cars were equipped with a carburetor.
In the world now, the land of electronic fuel injection, carburetor work is a dying art form, but one that we’re still tooled up and ready to handle as your specialty shop.
Our comprehensive cleaning process begins with the careful removal of the carburetor from the engine. We then disassemble it, meticulously cleaning each component with specially formulated solvents and brushes designed to reach even the most inaccessible crevices. We pay particular attention to the jets, which are especially susceptible to clogging. In some cases, we may use ultrasonic cleaning to remove stubborn deposits. This high-frequency vibration technology dislodges even the most tenacious grime without causing damage to the carburetor’s delicate components.
Once every part is spotless, the Holley power valves checked, and Edelbrock step-up springs set, we reassemble the carburetor with precision, ensuring all gaskets and seals are in perfect condition. These components are vital for preventing air leaks and maintaining the correct mixture. Finally, we reinstall it on your engine and fine-tune it for optimal performance, adjusting the idle speed, mixture, and choke settings to ensure smooth and efficient operation.

While cleaning is essential, you can take proactive measures to maintain your carburetor’s cleanliness and longevity. Using a high-quality fuel stabilizer helps prevent the formation of harmful deposits, especially during periods of storage. Fuel stabilizer prevents the gasoline from oxidizing and breaking down, which can lead to gum and varnish buildup in the carburetor. Opting for non-ethanol fuel whenever possible minimizes the risk of corrosion and damage to the carburetor’s delicate components.
Ethanol, a common additive in modern gasoline, can attract moisture and cause corrosion within the carburetor. It can also degrade rubber and plastic components, leading to leaks and malfunctions. By choosing non-ethanol fuel, you can safeguard your carburetor and ensure its optimal performance for years to come. However, it’s important to note that non-ethanol fuel may not always be readily available. In such cases, using a fuel stabilizer becomes even more crucial. Additionally, if you must use ethanol-blended fuel, consider adding a fuel system cleaner periodically to help combat the negative effects of ethanol.
