Engine running at idle with the rod VCV to fuel injection pump connected?

The engine is not running. The Mityvac provides all the vacuum necessary for the test.
The linkage is connected normally per the FSM.
BTW, 12.5" isn't a magical figure. It can be less than this value if the shifts are too soft for your own requirements. The SD is currently at 8" and I still get no banging.
