Dixie Narco - giving 2 for 1

[SilverDuck]

I have a Dixie Narco 600, 3 deep can machine.  One the first column, it tends to spit out 2 Mt Dews for the price of one.  No other column does this.  It is a wide column, and the other wide columns seem to work fine.  Because I have no clue what I'm doing, I decided to move the rear spacer to set it up for 2 deep.  This seems to work much better, but I'm still not sure what causes my machine to give 2 for 1's on that one column.

Any guesses?

My guess that the plastic wheels, in front of the vend motor, is adjusted wrong.

yep, the vending disks on the columns motor may be set wrong, check the diagram on the door liner.
