Im glad you were able to arrive to a certain conclusion with my experimenting with this Carburetor, though I do not wholly agree with your assertion. My initial goal was not to surmise if the UN2's performance was equal to or greater than that of the Rochester, but if it helped you to come to that initial conclusion, then that is a good thing, though it is still a bit too early to conclude that as of yet. There are still other avenues I can explore before we have the final word. As I mentioned from the beginning, my purpose for trying this carburetor out was to gauge its quality, and craftsmanship, and also its utility with our stovebolt engines, not necessarily its performance. Seeing as how no one on stovebolt.com had tried this carburetor out, I believe this experience has been favorable, and shines a good light on this carburetor. Also, something to consider, one does not always chose a carburetor depending only on all out performance. If that were the case, we would all be running Fuel Injection, which gives the optimum air/fuel mixture for performance, driveability and fuel economy. For many reasons we continue to run Carburetors, be it Rochesters, Carters, Zeniths, Daytonas, etc. My sole experimenting as of yet has been on my 261 c.i engine, but there are still many other engines one could try this carburetor on, for example the 216 ci or the 235 ci, maybe even the 250 ci. and the 292 ci. Also,one always has the option of running a dual carburetor setup or even a triple carburetor setup, which I think this carburetor would lend itself well to, if performance is what your after. I believe that so far the UN2 has proven to be a good alternative if one wants good performance, great drivability, and quality of craftsmanship, but everyone can decide for themselves and come to their own conclusion on that.
