[QUOTE="pierrox, post: 641526, member: 26374"] The balance pipe should go between the manifolds, not the carbs. The vacuum port on the carb is for the ignition advance. If you have CBPerf manifolds, they have a port for this. If you have the short Empis, they need drilling. I run the servo on mine off a T between the manifolds and 0 problem. And one carb vacuum goes to the distributor, though I have a 123Ignition so I could adjust it. On a regular dizzy, you probably need to use the vacuum from both carbs (therefore with a T) to get more succion as the short manifold create way less vacuum than long manifold to a central carb.
