fatten the motor up on the top to flush and turn the low end out a turn and half form where it at now.
also change all your fuel lines then do this
start the motor and lean the bottom just a lil if need to get to start then turn in the top end then do the low end to me it sounds like the low end way to lean
and also another rule the leaner the motor the lower your ideal screw need to be or how far out
the richer the motor the higer it need to be or turned in
