Why choose a WEBER 40 DCOE?

The WEBER 40 DCOE is a proven choice for classic engine builds where increased airflow and extensive carburettor tuning capability are important.

On a 1275cc A Series engine, the DCOE architecture provides a wide range of tuning possibilities through its selection of jets and other calibration components.

It is particularly suited to projects where throttle response, airflow and carburettor adjustability are priorities.

Typical applications include:

• upgraded classic road cars
• A Series engine builds
• fast-road MG Midgets
• tuned Sprites
• historic performance cars
• classic competition and motorsport projects

The 40 DCOE is also supported by a wide range of genuine tuning and replacement components.

Low Profile Throttle Linkage

A key feature of this kit is the Low Profile throttle linkage system.

Its compact design is particularly suited to the MG Midget 1275 installation, providing a practical throttle-control solution around the WEBER 40 DCOE.

Beware of WEBER Copies

Many WEBER-style copies are now available on the market.

While their purchase price can be attractive, machining quality and internal components can vary considerably. Jets and other calibration components may also differ from genuine WEBER specifications.

This can make accurate tuning more difficult and restrict access to genuine replacement components.

For a performance MG Midget / Sprite installation, we recommend choosing a genuine WEBER carburettor.
