I am working on a 1978 Spider Veloce (have not yet got the car running yet), in any event I am working my way through the ignition system. I am planning on changing the points (among other things), both sets. The distributor is a Marelli with the centrifugal mechanism ABOVE the breakers. I cannot determine how the centrifugal mechanism is removed so I can get to the points?? My manuals don’t seem to provide this information? Can anyone give me a hint? Thank You in advance.
