Vendorlator VF-148-bb won't drop soda

[FOWL1]

I know this post is old, but I just had time to work on the VF-148-BB.  I have the timing set correctly, but I'm still having an issue wit hthe dropping of the sodas.  The first time it dropped 2, then on a different selection dropped nothing and the other selections nothing.  At this point, I'm wondering if I'm loading it correctly.  The schematic picture shows if the screw is on the right side in the site, load the front first.  Likewise if the screw is on the left side in the view, load the back first.  I've done that several times.  I'm wondering if the bar that runs from front to back needs to be set in the middle of whichever one is being loaded.  The bar flops from side to side and I'm wondsering if the column that is loaded needs to have the can sitting on top of that bar instead of the bar being set to the side it flops to when loading.  Would anyone have any idea about it?  My wife is to the point of telling me to get rid of it.  It gets cold and stays cold.  I'm sure it has to be something very simple to get it to vend.  Please help before I have to get rid of it.
