Thanks (and sorry for calling you bob in my first reply!!) i'll keep playing with it.

I'm getting close and she sure does run a treat in the higher rev ranges. Its just the damn idle or lack there of

One thing i'm thinking is the throttle stops are letting the throttle bodies close just a smidge too much - potentially they are worn just a touch (although not showing any other signs of this)

The relationship between them opening and the pump arm seem to be spot on once you introduce some throttle - i.e.: part load mixture measurement is spot on and so is idle (albeit with some throttle) and it runs a treat with some revs on

If i wind up the throttle body stop position to stop them closing quite as much isn't this basically just having the effect of having a bit of throttle on and not changing the air / fuel equation between the pump and the throttle valves ????
