Did you put the accelerator pump rod in the right hole. You should have several options (2-4).

So since it works good with the choke partially closed, cutting back on the air entering the carb, it is apparently running lean off idle........so it may possibly be a vacuum leak around the carb gasket or as already said the accelerator pump rod is not in the correct hole, so it isn't getting the fuel it needs to match the air coming in.
