I've got a 76 260z with the flat top carbs. It was running rich an gradually getting worse to the point where it ran like a bag of ...... coughing and spluttering anywhere in the mid range. Idled rough, but went ok flat to the boards. A bit of investigation let to me putting a blank gasket on the accelertation valve on the offending carbie. Its a round bit on the side, about 30mm in diameter with 3 screws holding it on. Problem solved. Fixed the spluttering and got normal fuel economy again. I'm not sure if it affected the acceleration, I use it more as a grand tourer but it still gets up and goes fine, so if it did it's not much.
