Interesting - I did have a clog in one of the little brass tubes attached to the triangular block that goes in the middle of the carb (I'm not sure what the proper name is, I've seen it labeled "idle fuel pick up tube"). I unclogged it and now it idles easily with the choke off and gas is dribbling from both the cylinders on the "venturi cluster" (again, not sure of the proper name).
