Weber DGV carbs YOUR Opinions??
The DGV is a good carb. It is a progressive 2 bbl and popular with the /6, crowd among others. The carburetor is still sold and there is aftermarket support for it.
My experience with SUs exercised my repertoire of epithets. When properly sync'ed they worked fine.
If you're looking for a carburetor for an old Z car, how about a fabricated manifold with 3 DCOE 38s on it. The DCO is a sidedraft non-progressive Weber.
