text: No spark or intermittent spark, a problem that was fairly common back when distributors had vacuum advances was that one of the wires going to the pickup coil (pole piece) would break from the back and forth movement of the pickup as the vacuum advance would move it to control the timing, symptoms would be no start or that it would start and when you put a load on the engine and the vacuum dropped the vacuum advance would start to move the pickup coil, the broken wire would open the circuit and the spark would die.
