Review AUTOTRON New Choke Pull Offs Dodge Chrysler Plymouth Slant Holley

The Autotron CP492 Choke is a vital component for carbureted engines in certain Dodge and Plymouth models with slant six Holley 1BBL systems, specifically those using a Dodge Chrysler Powertrain Parts interchangeable distributor. This choke is designed to ensure a reliable and efficient cold start, particularly important in colder climates or during initial engine cranking.

The CP492 Choke is constructed from high-quality materials, with a robust metal casing that protects it from the harsh conditions of an automotive engine bay. Its design conforms to the original equipment specifications for the aforementioned vehicles, ensuring a perfect fit and seamless integration with the engine's electrical system.

The choke mechanism operates using a vacuum-assisted design, which means it utilizes engine vacuum to draw air into the carburetor, enriching the fuel mixture for a more responsive engine during cold starts. This design also helps to prevent the common issue of flooding, which can occur with choke designs that rely solely on an electrical current to enrich the fuel mixture.

Installation of the CP492 Choke is straightforward and requires no additional modifications or adjustments to the engine or electrical system. Simply replace the existing choke with this upgraded component, and you'll be on your way to improved cold starting performance and increased reliability.

In summary, the Autotron CP492 Choke is an essential and high-quality replacement part for Dodge and Plymouth vehicles with slant six Holley 1BBL carburetors. Its vacuum-assisted design ensures reliable cold starting performance, while its robust construction and easy installation make it an ideal choice for those seeking to maintain or upgrade their classic or vintage automobiles.

The Autotron CP492 choke is a carburetor heating system designed for use with certain slant six engines found in Dodge, Plymouth, and Chrysler vehicles, such as the Holley 1BBL carburetor. This device is intended to help improve cold starting performance by providing additional fuel and air mixture to the engine during cold weather conditions. Here are some potential pros and cons of buying an Autotron CP492 choke:

1. Improved cold starting: By providing additional fuel and air mixture to the engine during cold weather, the Autotron CP492 choke can help improve cold starting performance, making it easier to start the vehicle in freezing temperatures.

2. OEM compatibility: This choke is specifically designed for use with certain slant six engines, making it a direct fit for some Dodge, Plymouth, and Chrysler applications.

3. Easy installation: The Autotron CP492 choke can be installed relatively easily, as it replaces the existing choke mechanism on the vehicle.

1. Cost: The Autotron CP492 choke may be more expensive than a traditional choke or other heating system options, which could be a deterrent for some buyers.

2. Limited compatibility: The Autotron CP492 choke is only compatible with certain slant six engines, so it may not be an option for all Dodge, Plymouth, and Chrysler vehicles.

3. Additional maintenance: Like any other automotive component, the Autotron CP492 choke may require occasional maintenance to ensure proper function.

In conclusion, the Autotron CP492 choke can be a valuable addition for those who own a compatible Dodge, Plymouth, or Chrysler vehicle and experience difficulty starting in cold weather. Its ease of installation and potential for improved cold starting performance are significant advantages. However, the cost and limited compatibility may be drawbacks for some buyers. Ultimately, the decision to purchase an Autotron CP492 choke depends on individual circumstances and priorities.

Recommendation: If you own a Dodge, Plymouth, or Chrysler vehicle with a slant six engine and frequently experience cold starting issues, the Autotron CP492 choke could be a worthwhile investment. Weigh the potential benefits against the cost and limited compatibility before making a decision. If your vehicle is not compatible or the cost is prohibitive, consider other heating system options or modifications to improve cold starting performance.
