ICT Carburettor Base Gaskets

High quality fibre base gasket set designed to seal the carburettor to inlet manifold joint on engines running Weber 34 ICT carburettors. Supplied as a pair, these gaskets are essential for twin carb setups commonly used on aircooled VW engines.

The carburettor base gasket plays a critical role in maintaining a proper air-tight seal between the carb and manifold. It prevents unwanted air leaks (vacuum leaks), which can cause poor idle, hesitation, weak fuel mixture and general running issues. By ensuring a tight seal, the gasket allows the carburettor to correctly meter fuel and air, maintaining smooth engine performance.

Manufactured from durable fibre material, these gaskets are designed to withstand heat, fuel exposure and vibration, making them ideal for both standard and performance engines. The 36mm internal port diameter ensures proper airflow without restriction, while the 63mm stud spacing ensures correct fitment to Weber 34 ICT carburettors and compatible manifolds.

Features

• Fibre carburettor base gasket set (pair)
• Designed for Weber 34 ICT carburettors
• Prevents air leaks between carb and manifold
• Heat and fuel resistant construction
• Ideal for twin carb installations

Specifications

• Internal port diameter: 36mm
• Stud hole distance: 63mm
• Material: Fibre
• Quantity: 2 gaskets (pair)

How It Works
These gaskets sit between the carburettor base and the inlet manifold flange. When tightened down, they compress slightly to create a sealed surface, preventing unmetered air from entering the engine. This ensures correct air/fuel mixture, stable idle and consistent performance.
