The Philip screw on top of the carb should be taken out. There's another jet under the screw that should be cleaned out with some carb cleaner. I believe it the low speed jet.
I had an interesting problem, the choke butterfly was stuck in an unusual position and would not move. Somehow it went past the closed (choked) position and now was open and would not return being wedged in the space. The butterfly is a thin steel diaphragm that rotates on a plastic shaft that is actuated by the choke rod outside. You can see four (two each side buttons that hold it there. I tugged on it with vice grips and it slid out of the plastic rod, got it BACK into the proper position and pushed it back through. I am going to go ahead and clean the jets.
