Jerry, I have a Carter YF 964S carburetor on my 216 that will definitely NOT mount on a 235 manifold. And from what I know about the YF2100 series is that they will ONLY fit 235 or 261 manifolds. But I believe the throttle bodies will interchange between the bowl sections of the two series YFs. I believe the venturis are sized differently as well. But what you say about calibration differences is true. There are no "one size" carburetors (that will work anyway.)
