Zeniths are fine with a std 2.2t, however they are hard to set up if you change the configuration of your engine.

I was using them on a 2.0 with S pistons and E cam. I found that I could not get parts required for modifying the carbs to the Revs I wanted to use.

Venturies are impossible to get Jets can be redrilled. Gave up on changing emulsion tubes.

While they are a good carby there is not the knowledge or parts that are available for webers.

Go with the webers I gave up after about 6 months of stuffing around with the zeniths.
