Dave,
I guess you are right. After I put the Carter on, I decided to rebuild the Rochester, just for fun. I found that the power valve was installed incorrectly, (ball and spring in the wrong place) and the end of the power valve was split. No doubt this contributed to the bad gas mileage. This carb was a rebuilt unit I got at the FLAPS some years ago. It was also leaky.
The Carter is working so well for me that I haven't bothered to try the Rochester again. It just sits on the shelf.....
