[6pack] Rear carb Bypass Valve Adjustment

[Rick Norris]

While having the same struggle as you've described with my rebuilt ZS's, I was
informed that the rear carb's bypass valve can easily be adusted by simply
pulling the throttle linkage to full open thereby exposing the
adjustment screw to a small screwdriver. I had already explored the depth and
breadth of my expletive vocabulary with no particular success!
