Rob,
Smaller air corrector jets will richen the mixture at top end.
If memory serves me right with 28mm chokes I run 125 mains f16 e-tubes
and 160 air corrector sets. If that doesn't help then make sure you have
adequate fuel flow at high RPM; i.e., float level, fuel delivery
(plumbing) design or fuel bowl vibration from engine.

Hello folks I have just spent some time tunning. I can get a good
Air/fuel
curve and power all the way up to 5500rpm At 5500 she is still making
power
but the A/F is shooting up into the high 15's --16's and i just have to
back
out The fuel pressure remains at 4 lbs the gage has be ckecked aganst
another >> the jet changes will only make me rich at the lower rpm
she'll
stummble to get cleaned out but still goes lean . We have been all over
the
board with jetting .With aprox 30 hours of tunning We have not been
able to
get a way from the high A/F at the higher rpms Drilling the pump jet
helped
but only put off the running lean >>Its a Tr-6 Moss's 40 over
