Ford 428 with a Ford dual carb manifold smoking out the pax side after warm up. Blip the throttle and a puff of Black smoke comes out of the right side pipe. I started gearing up to change the intake manifold gasket but I'm not seeing anything jump out at me examining the plugs except all 4 on the right side are Black compared to the drivers side. Breathers in both valve covers, no PCV installed, timing right on 18 at idle-38 full in, float levels good, drain back holes in heads look clear. I installed Autolite 3926 plugs instead of the 3924 thinking the plugs might be too cold but no change. Idle air screws out 1 turn on all 4. Thanks....
