New-Old-Stock set of 2 x Italian Weber 50 DCO/SP Carburetors for Opel 2400 Rallye

New-Old-Stock set of 2 x Italian Weber 50 DCO/SP Carburetors for Opel 2400 Rallye

New-Old-Stock set consisting of 2 x Weber 50 DCO/SP carburettors for Opel 2400 Rallye.

This is what we consider, already, our find of he year!

This is an authentic, unused, set of 2 Weber 50 DCO/SP carburettors, especially made for use on the Opel 2400 Rally engines but will fit of course all engines and manifolds that can accommodate 50 mm carburetors.

Produced around 1980 in Bologna, Italy, this is THE Must-Have for the Opel- freak!

Please note that Weber still has 50DCP/Sp's produced in Spain nowadays but that this concerns an authentic, matched (!) Italian set.

Apart from a slight quality advantage compared to the Spanish production items, the most important is that these carbs are period-correct for creating or restoring one of Opel's Rally Beasts.

In Factory Rally Trim, these 2400 engines boasted, reputedly, over 350 HP with Maestro's like Walter Röhrl at the wheel.

This particular version, 50DCO1/SP 8D, has 4 progression holes.

As this is the DCO/SP version (Doppio Corpo Orizontale / SPort or Twin Barrel Horizontal Sports) these carburettors do NOT have any form of Cold-Start Device (or choke) fitted.

The set will be supplied as depicted, each carburetor in its original box.

Accessories and virtually all jets and tuning parts for these DCO/SP's can be found HERE.

They are supplied with the following jetting recipe:

  • 46 mm choke / venturi (no other sizes available)
  • 180 Main Jet
  • 65F8 Idle Jet
  • F7 Main Emulsion Tube
  • 45 Pump Jet
  • 100 Back Bleed Valve
  • 250 Needle Valve

The trumpets measure 42.5 mm in length.

These carburetors might require a DCO/SP mounting kit which can be found HERE.

Only 1 set available!

40DCNF-NOS
New-Old-Stock Italian Weber 40 DCNF Carburetor

New-Old-Stock Italian Weber 40 DCNF Carburetor

New-Old-Stock Weber 40 DCNF 100-250 carburettor.

These are the original DCNF's, Made in Bologna, Italy, produced in the mid-1980's.

These are so-called "New-Old-Stock" carburetors which means that there were produced "in period" but have never been sold to an end-user and consequently have never seen any action.

Please note that Weber produces the 40 DCNF again in Spain nowadays but that this concerns an authentic Italian carburetor.

Apart from a slight quality advantage compared to the Spanish production items, the most important is that these carbs are period-correct which is important for restoration projects where authenticity counts.

Over the course of the last 35-odd years, some parts have been scavenged and used in other products but we will complete them, largely to your specification, before we ship them to you.

To leave nothing unclear, following is the exact specification:

NOT to be altered:

  • Throttle Valve Diameter: 40 mm
