U20 Oil Pump Drive

[RIckSRL@cs.com]

I had the distributor out of my engine today and noticed that the geared 
shaft that drives both the oil pump and distributor seemed a bit odd. The 
slot at the top of the shaft that drives the distributor is ground off 
center. Now, I also noted that the distributor drive is pinned to the 
distributor shaft to allow it pivot to make up for a slight misalignment.
Does anyone know why the shaft is cut off center? Seems strange.
