My recent aquisition is setup with an Offy 2 pot manifold on a 215". There are 2 Holley 1904s on it. The vacuum from the front carb is hooked up to the Load-O-Matic distributer. I can feel a bucking at cruise at any speed above 25MPH. It runs strong when I'm on the throttle. I am suspecting the carbs should be rebuilt. I do have a couple questions about the Load-O-Matic. Should the vacuum signal from both carbs be fed to the distributer or is it normal to use only one? Can the Load-O-Matic be run off manifold vacuum?
