Russ,

You are going to HAVE to drop the front and perform the mechanical 
alignment of the gear train.

The veeder root counter will need to be set to 7000.0+.  This will be 
with the KC at its 10 turns fully CW.

Make sure the MC switch detent is set to 7.

Align all gear lobe pointed portions to align with the marks on the 
front of the slug racks.

It sounds as though someone just threw it together without paying ANY 
attention to the mechanical positioning.

Have you got the Y2K manual?
