HELP: What Carb is This?

[r1lark]

Need some help. I don't think this is a Patrol carb (at least it's not like the one on my Patrol best I can remember), but 95% sure it's a Datsun carb. A lot of y'all are into other Nissan/Datsun vehicles other than Patrols, so hoped someone would recognize it.

I am sure that it is pre-1969, since it's left over from the family's dealership that closed in mid- '69 when we moved to NC. There is no tag or other identification marks - it looks like it has been kitted then not installed on a vehicle after that.

Anyone recognize it, or maybe can at least point me in the direction of what it may be off of? Thanks in advance for any insight!

My 64 and 65 Datsun pickups have carbs that look like that, except mine have glass covers on the float bowl with an etched-in fuel level line. (and the Nikki name) My trucks have 1200 cc engines.
What are the he diameters of the bores and intake filter attach points?
I’ve got some info on sizes and jetting for these.

Thanks for the reply Bill! Yes, the Nikki carbs that I have seen (many years ago when all I drove were Datsuns) had the clear cover also.

The Primary bore is 28 mm, and the secondary bore is 30 mm. The fuel inlet, now that I look at it, is pretty weird. It has internal threads, smooth on the OD, but two small holes from the ID to the OD. Don't remember an inlet like that, but then again it's been about 37 years since I let my last Datsun go. The OD of the fuel inlet is 0.400", and the internal threads appear to be 5/16-24.

Thanks!!

Sent a PM... Also, That fuel inlet is part of a banjo fitting. I've become intimate with that carb several times in the past 47 years. Its currently working well.
