Thanks to all that answered. Seems the Revflow is a little better than the Posa, with some of the same idiosyncrasies.
I suspect that either carb could be made to work fine by anyone that knows how to properly adjust mixture and takes the time to contour the needle just right. I also suspect that this is another area where having an oxygen sensor and mixture meter would make a world of difference. Most people just know that the engine is running bad at some power settings and can't tell if it is rich or lean. For those people, tuning one of these carbs without a mixture meter probably would be a nightmare. We will see if I have the same feelings after I start to twiddle with it.

It refined some of the poor areas that the posa just could not do right, like the mixture control and positive fuel shutoff. As Steve said, for some of us, the needle still did not cover all the range of performance. I also custom carved a needle to meet my needs. Unlike the posa, at least this could be done, with a good chance of success. Joe at Revmaster will work with you and even custom cut a needle for you if necessary. I like the carb and will continue it's use.
