well, with a stock cam, and stock style heads-which are great for that velocity, i'm sure that 570 is nothing short of fantastic for all around performance...not to mention that most of the time vac sec carbs provide better driveability and smoother power curves for hoover inducing low duration cams
also, if out of all the carbs you used, the spark advance port never worked-that would definitely have something to do with off-idle and midrange operation. it's kinda wierd that none of them ever pulled any vacuum though...i've never seen that one, unless it's plugged.
just cking-your vacuum diaphragm in the dizzy is good, right? i've had one go bad before and couldn't figure out why i had a little vac leak, and my get up and go got up and left...easy fix though.
