Can anyone identify this carb?
We have a 1982 RX-7 that long before we got it was setup and raced and now we run it in the 24 hrs of Lemons. We now have a 1983 RX-7 and thinking of making it a 2nd team car and who ever setup the 82 did a great job and we want to duplicate the setup. One of the items is the carb which is visually different than the stock carb on the 83. So we are hoping a RX-7 guru can tell from the photo what we have. At this point do not want to remove the carb in the photo to look for model numbers etc since we have a running car.

It's had the somewhat bizarre Circle of Willis fuel inlet replaced with AN lines directly to the needle valve banjos, and the choke horn milled off. I am assuming that the smaller AN line is a fuel return. (Yes, there are fuel passages inside the carb top connecting the two sides)
I am 99% certain it is not a Yaw carb, as he retained the stock fuel inlet, removed one of the annular rings on the primary boosters, and bored the venturis out.

🤔To me that looks like a heavily modified early Nikki carb...

Looks like a mostly stock FB Nikki that has been stripped and had the AN lines added. Can't tell for certain what all has been done to it from just that photo, but the venturis are stock, the throttle shafts aren't messed with, and the boosters haven't been trimmed either. So yeah, stripped stock Nikki with some AN lines. Might have mechanical secondaries but you can't tell from the photo.
Curious what you're seeing here peejay. I don't see any changes to the air horn other than that the choke itself is missing.
