The forward carb has tons of vacumm and the rear carb has almost none. This is a newly built engine and im starting it up for the first time. What would cause the one carb to have vacumm and the other none, when they pull off the same intake? My vacumm advance is tied into the forward carb and the rear is blocked off. Does that make a difference? It also seems that forward carb is pulling a lot more fuel, but i can't verify that yet. Cecil......... | | |
