That replacement carburetor looks a lot like the Daytona universal carburetor sold by Carb Doctor out of Texas. If it is, it is pretty much a Zenith 28/228 carburetor. I purchased one for my 37 IHC D2 so I could keep it on the road while I got parts and machining done on the original Zenith 23.
Not a bad carb when compared to the worn out original. (It is a universal so Venturi size, etc may not be exactly the same.). Setup was easy and it does the job. As mentioned earlier, the choke is manual. The Sisson won’t work. The height is slightly shorter. I thought the throttle shaft rotation was the same as on my D24 but didn’t spend much time comparing it to the Carter as I was more focused on the Zenith it was replacing. I can see where the air cleaner might not clamp on also.
If you need more info on the throttle rotation, I can verify it against the BB in my ‘48 but the folks here are very knowledgeable and usually catch that sort of thing right out of the box.
best of luck
