273 carter afb

Well I had time to take the carb off and check it out I turned the idle screw out a few turns and the primary throttle blades close fine and cover the vacuum ports for the distributor fine. So now I guess that I have to keep the idle turned up because of the cam and that causes the vacuum at the distributor port at idle. With the distributor vacuum line disconnected the engine smooths out but still sounds pretty lumpy at the tailpipe. So I guess its back to the cam change and if that dont work I will take the offenhauser manifold off and find a stock early 273 cast iron 4 bbl manifold.

Here is the link on the cam
