As luck would have it, I eventually became an instructor for the Ford VV carb repair. After a few years experience with it, I came to understand it and tried to convince my "students" that it was truly a fine piece of engineering and would operate as smooth as any carb out there and was the closest thing you could get to fuel injection. The second generation VV had a feed back actuator installed and when adjusted properly, the air/fuel mixture responded directly to the engine load instead of just throttle plate movement. Probably the reason most mechanics disliked (hated) it was other than idle speed, all adjustments required removal from the engine and the use of a dial indicator to properly set the CER (cold enrichment), CVR (control vacuum regulator) and accelerator pump. It probably would have been used longer, but electronic fuel injection was just around the corner and soon took the place of almost all the carburetors.
