 Ignition begins when injection begins. 
The governor and throttle lever and fuel screw all have only one final effect, which is to alter the point at which the spill port is exposed, at which point injection stops. The Bosch literature on VE Pumps explains. Hagar, open a pump & take a peek.

Moving the Pump does not control ignition point -- it moves 
Injection point.
