So are you running dual carbs right now & its hesitating?
My method is to use a single carb intake, wring the carbs out 1 at a time and find my favorites (as I said the mid-size carbs are cheep). Some of them do hesitate, but some I can punch right off the line to the floor. Get a pair like that and they might work as duals.
What about initial timing, sometimes that helps or a quicker timing curve? A retarded cam will also make it more prone to hesitate, have you degreed the cam in so you know where it is? Of course gears don't stretch like a chain but I always check anyway
I show the little 1-1/16" "B" used on the 60-62 truck, 235 economy option.
Some of the old 216 Carter BB carbs are also this small but of course theyre not Rochesters.
