Very informative, and the examples above and in link (posts #8 and up) are pretty much what I'm dealing with while I await the arrival of a 10.5" PV. I have my jetting set pretty close for cruise, and wot with a 6.5" PV (all I have atm) but it needs to open sooner, and I also now have a slight tip-in hesitation that wasn't there before. Holding off on any further tuning until I get the 10.5" , then I'll settle on jets, then accelerator pump cams, and/or squirters, and looking at the primary blocks various restricters etc
