Bonneville America Forums Forums Technical Forums General Tech vacumn ports on intake and carbs

i remember a while back reading a post about hooking a vacumn line up between the carbs instead of the vacumn plugs being put on after ai removal. do both the carbs and intakes get hooked together with a line or just the carbs???
what does this accomplish, better idle, or does it help balance the carbs so that they pull the same vacumn??? thanks cliff

do the carbs, it does help idle and it does balance them a bit better than without. plus hose does not wear as fast as the caps do
