Introduction
Upgrading your VW Kombi Type 2 with a dual carburetor conversion kit can significantly enhance engine performance, providing improved throttle response and increased horsepower. This guide outlines the essential steps and considerations for a successful installation.
Understanding Dual Carburetor Conversion
Dual carburetor systems deliver a balanced air-fuel mixture to each cylinder bank, optimizing combustion efficiency. This setup contrasts with single carburetor systems, which may not distribute the mixture as evenly, potentially leading to performance inconsistencies. By installing dual carburetors, Kombi owners can experience smoother acceleration and better overall engine performance.
Installation Steps
-
Preparation
- Ensure the engine is cool and disconnect the battery to prevent electrical hazards.
- Remove the existing air cleaner, carburetor, and intake manifold. Keep track of all hardware for reassembly.
-
Installing the Dual Carburetor Kit
- Attach the new intake manifolds provided in the kit to the cylinder heads, ensuring a proper seal with new gaskets.
- Mount the carburetors onto the manifolds, securing them with the supplied hardware. Avoid overtightening to prevent damage.
- Install the linkage assembly, adjusting it to ensure synchronized operation of both carburetors.
- Connect the fuel lines, ensuring leak-free joints. It's advisable to use new fuel hoses and clamps for safety.
- Reconnect the throttle cable to the new linkage, adjusting for smooth and responsive throttle movement.
-
Final Adjustments
- Reconnect the battery and start the engine. Allow it to reach operating temperature.
- Adjust the idle speed and mixture screws on each carburetor to achieve a balanced and smooth idle.
- Synchronize the carburetors using a synchronization tool to ensure even airflow, which is crucial for optimal performance.
