These are the uncommon Type-R PHH, that I bought years ago 'jetted to suit 1400-1500cc' so your probably right about the main jet. The Type-T (for toyota) are the more common ones, they do however share the same jets.
I reckon I might just have to invest in a handful of jets and start some experimenting.
As for the different Pilot Jet sizes, that seems to be a common thing on these carbs, where one side is different to the other. I might just put the same size in all round.
