This is a Brand New, GENUINE Spanish-made Weber 40 DCOE carburettor with ram tubes. These are one of the most popular aftermarket sports carburettors fitted to most 4 Cylinder and some 6 Cylinder motors around the world. Generally an instant power and torque increase from most factory standard carburettors.

40 DCOE's are an excellent choice for motors 2.5L and below, especially if you are going for a throat per cylinder application. Generally 45 DCOE's would be used for more race type of setup where revs are going to be constantly higher. A 40 DCOE will still give you that sporty feel and great induction noise, just without the flatspots that a 45 DCOE would produce for small motors.

These model DCOE's are a must if you are looking to get the best performance out of any engine. The benefits of fitting DCOE's are their fine tuning capabilities. With DCOE's, you can alter the following:

  • Choke Venturis
  • Booster Venturis
  • Main Jets
  • Air Jets
  • Emulsion Tubes
  • Idle Jets
  • Idle Emulsion
  • Pump Jet
  • Cold Start Jet
  • Needle Valve Size
  • Idle Air Bleeds

A multitude of tuning areas that you just cannot do easily with most other brands of carburettors.

Know that you're buying a genuine Carburettor. See in our gallery for the photo that outlines where to tell if the carburettor is Genuine or not.

The ram tubes are made from a high quality, spun steel process; not a cheap chrome-dipped procedure.

  • Float levels to Weber Standard
  • Throttle Butterflies are aligned and moving freely
  • Mixture screws are set to a standard stetting
  • Idle Speed screw is set to a standard setting
  • Idle Air Bleed screws are set to zero

These are done so that we know you are getting a product that is more likely to bolt on and run for you without any hassle.
