it probably doesn't fall off a cliff straight away but plateaus till like 5, mayyybe 52 and then just stops making power.

the 650 is probably great for fuel mileage and i'd bet it's super crisp throttle wise around town, but that's not doing you any favors.

I am sure you are right!
I haven't had a chance yet to switch between the two carbs to see if i noticed a difference. I am also considering buying the avs2 800 although that is not a double-pumper, and i believethe ratingsto be lower. My holley 750 has the old straight leg boosters which i heard doesn't play well with the air gap intake for fuel break up and distribution, but that could just be forum rumors.
Also, the reason for the summit carb was because it was based upon the autolight 4100, which is considered one of the best off road carburetors for incline angles and not uncovering the jets. I deal with a several steep inclines in Vermont
