Weber 40 DCOE Carburettor

40 DCOE 151 - Genuine Weber Carburettor

Sale price  $850.00 Regular price  $890.00

The Weber 40 DCOE 151 is one of the most legendary performance carburettors ever produced. With its side-draught design and fully modular jetting system, the 40 DCOE allows precise tuning – making it ideal for road or track,  4- and 6-cylinder engines where a 45 DCOE would be too large.

Built with Weber’s signature durability and engineering precision, the 40 DCOE remains the preferred choice for performance restorations, vintage motorsport, and anyone wanting to unlock the full character of their engine.

Key Features:

  • High-flow side-draught design for strong, responsive performance
  • For single or multi-carb arrangements
  • Fully tunable with interchangeable jets, chokes, emulsion tubes, and venturis
  • Smooth throttle response from low RPM through to the top end
  • Durable, proven Weber construction built for long-term reliability
  • Perfect for twin- or multi-carb setups on engines requiring balanced airflow
