Here is the repo SD linkage from Fab Craft I just purchased:

The second photo is the progressive linkage my setup has .....which runs the rear carb first and then with uneven pedal pressure it opens the front carb.
I assume that this Fab-craft linkage is not progressive like my current setup.
Is this not the same as the factory setup?
