AFAIK there is no 'screw' for adjusting as you describe - just the idle mixture adjustment
This might give you an idea of how the jets cover the throttle opening
Pilot jet & screw- 0-25%
Needle - 20%-75%
Main Jet - 70%-100%
Have you checked the AFR on a dyno yet?

A lot will depend on the air filter. If you are running without an airbox then they tend to run quite lean so maybe this is your problem. Either way I
would try and resist the temptation to use it too much until you get it tuned properly - anything at this stage is just guesswork and could end up
very expensive
