I know most are stromberg cd and two SU's but what's this one?

Anyone interested in buying the surplus once I decide which to use.

Looks like a hitachi carb with an adapted manifold, maybe Viva?
CD stromberg's are $hit.
SUs are great, easy to tune by changing/sanding needles, but those look like tamper proof ones, so not sure if any good.

Your right about the manifold, it is a modified Viva one, that will fit straight onto my engine.

Are the Hitachi carbs any good?

SU is apparently a H4 (left) and an H2 (back right)

Hi Ian
Many years ago I remember a customer who had a viva with one of those hitachi carbs on, it seemed to go just a bit better than the others which at the time had downdraft solex carbs. So maybe not a bad bet.
For something different what about getting a sidedraft weber/dellortos and make your own manifold, saw one on a chèvette, the carb was mounted over the top of the engine. Went very well. You'd only need a small one and it would have all the right sounds.

Pretty straightforward to modify an SU carb. According to Vizard's notes, possible to make an 1 1/2" (H4, HS4) flow like an unmoved 1 3/4", which should make it good for around 100hp (not that any Chevette/Viva ever made that much).

Yes, they are good carbs, very reliable. Seen on many small - mid jap cars. However people seem to change them over to Webers, Subaru 1800 EA82s have them but are replaced with Cortina carb. Probably it is a size thing more than anything else. The one you have might have come off a 3K corolla, Datsun 1200 or something similar.
