Brant, you might go I size up on the pilots. Opening the mix screws actually will richen the mid range slightly. That might be what it's begging for.
If it's running a bit rich on the highway it might be because you have to crack the throttle a little and scavenge the mains to get it happy. I'm running 1 size over on mains and pilots and I'm still a tick lean with my Mac exhaust and the
older style carbs.
I really dislike the late carbs, they were designed to make OSHA happy not the engine.
