Ford 428 rich on one side only
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....

Are you sure it's rich and not getting oil?
Usually black smoke is rich, blue is oil. Have you checked your jets to make sure they aren't plugged? Idle ports clean? Check the squirter and see if they are squirting equally. Try squirting carb cleaner down all the air bleeds (carefully). |
intake is probably sucking oil from the bottom of the runners
