I've just installed dual 34 carbs (EMPI) with the equalizer tube between both manifolds and can't get a good fuel mixture. (The distributor is vacuum and centrifugal.) Tried both sets of jets. Would timing be causing this problem?? Or maybe I need to connect the vacuum from both carbs to dist?
Any help would be great! |

In the diagram form post number 6 above the item number 6 upper is the seat and the item number 6 lower is the needle. The float is number 7. The float has a tab that pushes number 6 lower into number 6 upper and cuts off the fuel supply. You need to bend the tab very carefully to obtain the correct distance from the bottom of the float to the face of the fuel bowel gasket. If the float sets to high in the fuel bowl it will allow to much fuel into the bowl causing it to give a mixture that is too rich.
