DCOE?Carb Mounts are required to mount the cantilevered side-draft carbs. These cushioned mounts seal the carb against the manifold and allow for a soft mount, damping out any vibration transmitted to the carb body. Old Style, too, use the tried and true metal spring thackery washers to provide for float. The New Style, center relies on the four rubber bushings and steel collars for this anti-vibration mount. Solid mounts, below, have a solid rubber core and gasket material faces. Order one part number per carburetor.
