Yikes, TDC at idle. That distributor will definitely need recurved. The curve described in that FSM is asking for the idle speed, vacuum and timing to circle the drain (aka death spiral). As the vacuum drops the idle speed drops, as the idle speed drops the timing drops. As the timing drops the idle speed and vacuum drop even more and so on until the engine stops running.


In theory, there is no difference between theory and practice. In practice, there is.
