Yes, these are 1:1 linkage on both carbs. All 8 barrels at once, within reason as there is some primary movement before secondary but not much. These are not double pumpers, 1850 style. No sure how secondary idle gets fed. I knowing I add metering blocks to the rear for jet changes, the idle mix screws will not work as the carb bodies aren't drilled for that. Does that help?

Not enough for me.
