With this cam, not sure how low the idle can go. Before I opened the restriction, mixture screws were responsive. Remember the throttle blades drilled, so I don't have to open the throttle too far. Except for now since I opened the restriction
1400rpm is too high to try and adjust the mixture screws. i'm skeptical about being too rich if the only idle feed is two .033" jets. you don't think your pushing thru the needle and seats do you? I have you measured the seat orifice to see if it's in that .075" range? you may have more than one issue going on.
