Success..... Thanks Burdar.. Thanks John..
It might seem simple but I have come to the realization that I am the sort who has to think "out loud" before taking action.. maybe that has come with age.
The solution was to lengthen the 'Adjustable Intermediate Rod' from the upper bell crank, so it moves the Throttle Lever rearward. This causes it to increase Throttle Pressure sooner.
I now get proper upshifts, partial throttle downshift, and WOT downshift.
You can see the 'Adjustable Intermediate Rod' at the 12:08 mark of the video, or you can notice the freshly exposed steel on the rod at the back of the bell crank in the photo below, compare it to the first photo up top... Sorry the pic is sideways, my Mac does funny things.
Cheers,
