Are you running stock jets ? stock exhaust ? Any other modifications ?
On the primary carb , there is a pilot screw located just in front of the bowl . There is a cap covering the screw . Try resetting the screw to 2.5 - 3 turns out from lightly seated .
That might help the idle and very low end . What are you running for an air filter ? stock filtration set up ? Any at all ?

The specs for my 350 are :
Intake : .003" - .005"
Exhaust : .005" - .007"
I would think they would be very similar if not the same for the 600 .
I suppose it's possible that the idle circuit is still a bit dirty . Is there an in line paper fuel filter ?
