OK, hooked up my FAST air fuel ratio meter to my 496 Six Pack and did a little cruising. At idle I'm right around 13.5-1. But when I cruise at 20 to 30mph it runs rich in the 11.0 to 12 range. When I cruise in the 60 to 65 mph it's back to around 13.5-1 Do you think I should try a little smaller jet in the center carb to lean the lower cruise speeds out a bit? I'm tryig to find my paperwork from Harms. But I think I had 64 jets installed. Thanks
