thanks for any future help

They look like the standard Aseries carbies to me. Little fact though, they were actually used on other cars in the 70's and stuff like Hondas


no.1
no.2
no.3

my 1984 ford metior has twin downdraft hitachi's the same as you would find on the datsun

I do not recognise the first one. The second one is standard '71-3 (US at least) 1200 trim A12 carb.. that is it LOOKS like one. The smooth bell-like choke mechanism looks right for that carb. The third one looks just like my later model (B210) A14/15 carb, but I would need a pic from the other side (the choke mechanism) to make a match. It should have an angular black plastic housing with a metal ring and 3 set screws holding it in position.

There is a big carb article in the tech section with marking references and everything. You can probably find the info you need by looking up the markings.

DCG286 is a small-bore version 28mm bore as used on the A10 engine in Datsun 1000. Larger engines used the DCH306 with 30mm bore.

The 2nd one looks like a 1973 or newer A12 carb -- it has the anti-diesel valve (started in 1973) and the idle-stop thing for automatic transmission. It also looks to be non-North America judging by it is manual choke.

DSC306-51 is probably from around 1973-1977.
