Vacuum advance canister
Does anyone know where I can find a vacuum advance canister for an SD-220? And how do those 3 little plates work to hold the distributer firmly but still allow the vacuum advance to work properly. My truck's previous owner had the spring loaded cap screw so tight that the vacuum advance couldn't work. Once I corrected that problem, things were better but my canister only advances, it will not retard (or release) when the vacuum is disconnected or the engine is off.
