Review CARTER Mopar Thermoquad Carburetor Speed Manual Dated G0 fits 340 1971

The Carter 4972S Mopar 1971 Thermoquad Carburetor is a classic automotive component that is widely popular among enthusiasts restoring or customizing vehicles from the muscle car era. This carburetor was originally manufactured by Carter Carburetor Company for Chrysler's Mopar division and was specifically designed for use with 340 cubic inch V8 engines in 1971 model year vehicles.

The Thermoquad designation refers to the carburetor's unique quad-barrel configuration, which includes four separate barrels arranged in a square pattern. Each barrel is equipped with its own throttle butterfly valve, allowing for precise fuel metering and airflow control. The Thermoquad design also features a central throttle position sensor that monitors the position of all four throttle plates. This information is then sent to the engine management system for optimal fuel delivery and combustion.

This particular Carter 4972S carburetor is a manual model, meaning it does not come with an electric choke or automatic fuel pump. Instead, it relies on manual methods for starting and priming the engine. The carburetor is equipped with a mechanical fuel pump that must be primed manually before starting the engine. Additionally, the choke function is operated manually using a lever on the carburetor housing.

The Carter 4972S Mopar 1971 Thermoquad Carburetor is a finely tuned piece of machinery that requires careful installation and adjustment to ensure proper operation. It features a number of adjustable components, including idle mixture screws, main jet adjustments, and secondary idle mixture screws. These adjustments allow the carburetor to be fine-tuned to specific engine conditions and driving styles.

The carburetor is constructed from high-quality materials, including brass and chrome-plated steel. It features a durable, polished finish that looks great on any engine bay and is resistant to corrosion and wear. The carburetor also comes with a number of essential components, including a gasket set, fuel bowls, and float bowls.

The Carter 4972S Mopar 1971 Thermoquad Carburetor is a must-have for anyone restoring a classic muscle car or building a high-performance hot rod. Its unique design, precise fuel delivery, and durable construction make it a favorite among automotive enthusiasts. With careful installation, adjustment, and maintenance, this carburetor will provide reliable and efficient power for years to come.
