If your setup has the adjusting lines pulling the fairlead car aft, I'd love to see a photo of it—cause I have no idea how that would possibly work.
Here's an image of the Harken setup:
I realize that is how Harken describes the setup - I have now did the reverse because when I had it set up that way (as illustrated) - I didn't have the control I wanted when using anything less than a 150. Having the block aft, and the car reversed - allows wind on the sail to move the genoa car forward (when having reduced sail area) when releasing the tension on the adjusting line just enough to release the pin to allow it to go forward. To be honest haven't tested it with the reverse setup and will be installing another set of blocks on the track so I can change the setup at whim...
The problem really with the setup as illustrated in the diagram that it assumes that tension is on the tack line - when in some cases depdning on sail shape and size of sail - not necessarily viable.
Thats been my experience with using the setup in the diagram...
