John, almost sounds like you installed the wrong base plate to body gasket. There are several different ones and are all close. If you used the wrong gasket, it will cover and block the wrong passages and wont allow the carb to idle. Also (as im sure you know) dont run the mixture screws in real hard in the metering block it will dimple the screw and cause funky idle issues. My bet tho is the wrong body to base gasket.
