OK. Checked the carb 7040262. No port for vacuum on the left front corner of carb. Engine is a 428 +.30, Cam is 041 , 1.5 rockers. Stock piston Speed Pro 2882G. I'm going to drive it this weekend and see how good it starts while good and hot after a hot soak. Maybe I will revise my initial timing setting.
