48, 288 boggs down past half throttle

Working on a1948, 288 I8. As you accel, when you get around and beyond half throttle, the engine starts to bog down and loose power. This can be replicated while sitting still in neutral. I reset the points, inspected and cleaned spk plugs. The plugs were somewhat fowled. I tried retarding as advancing the timing and closed the choke as it was losing power. None of these things helped the condition. I acts as if it is too rich, when it does this. The carb appears the be a replacement unit. Any thoughts out there
thanks
