I've rebuilt the webers on the bavaria and have them synchronized well enough to move the car about. The webers dont have a ported vacuum access on the carb body and neither do the manifolds. the rear manifold does have one ported vacuum access but front manifold has only the port for the brake booster hose. Does anyone have any information on synchronizing the weber 32 36 carbs and where to access ported vacuum for use with a synchronizaion tool whether its a tool such as the carbmate or a simple vacuum gage. Any information on how to synchronize appreciated

The brake booster port and other manifold provides “manifold” vacuum not “ported” vacuum, meaning the signal is highest at idle with butterflies closed. This is what you want for synchronizing using a vacuum gauge like a Carbmate. Ported vacuum is zero at idle and increases when the butterflies open until it then drops off. Once the throttles open to a certain point, ported and manifold vacuum are equal. I’ve never seen a 32/36 without both ported (above the throttle plate) and manifold (below the throttle plate) take-offs. Some pics would be helpful because these need to be capped if not used for vacuum advance. The best way to synch these is with a Synchronmeter and matching dgav adapter as John mentioned.
