That's pretty much what I'm thinking, Dick. Having 3 carbs, each with acc. pumps, really limits the window of operation for the PV. I'm thinking it's just not needed most of the time. It's certainly not needed just driving around town.
I'm thinking it's window of operation is - during full throttle operation , on the tail end of the pump shots, and as the end carb main jets come into play. That's a VERY narrow window but, still one that needs to be addressed.
More tuning to come....
