Erm... 4 half turns.

I have mine set to about 45º less than two full turns.
Anyway, surely the mixture screw only affects the mixture at small throttle openings? By the time you've got the butterfly open far enough to reach 7000 rpm the contribution from the slow jet will be dwarfed by that from the main.
Have to say this sounds more like something blocking airflow, fuel starvation or sparks. I'm sure you've eliminated some of those, but wading back though the 500 entries on this thread would expose my eyes to too much of CRH's punctuation. :rollin
