Let me try and answer this one by one.

Correct, not a pass through hole. What happens is when the screw comes all the way out (which is the idle screw, phillips head) you have to pop that plastic piece out that is below the bottom of the screw. I normally use a small flat head screw driver and pop it out. Pop it out and spray carb cleaner all though that jet and the pathways in the carb.

Please explain this. I take it the main jet is not the emulsion tube from what you say here. The jet that screws out can not be banged out....right?
The main jet is the brass looking thing on the right side of the picture attached, the emulsion tube is the one on the left. What happens is the main jet you unscrew using a flat screwdriver (the fits correctly, cannot be too big) and then the emulsion tube is held in by the main jet. Once the main jet is removed that tube should just pop out with little effort. The emulsion tube is visible if you look though the main body if the carb (second picture) and you can tap it down to get it to release.

I believe that is the float bowl pin you are thinking of? Only thing I know of that has a spring. The idle jet is not inside the bowl of the carb but under the idle screw adjustment.

With the throttle closed, that jet at the base of the carb (with spring) will have to feed fuel into the stream of air. Or I am thinking of my training in Weber racing carbs.
The jet at the base of the carb needs to be just tight not too tight. Number of turns do not matter here as it just needs to sit there and the size of the hole in the middle regulates the flow.

The "jet" with the sprint (float bowl) is for fuel supply I believe, the bowl goes up when the bowl gets full and the pin cuts off the fuel supply. If you bowl is full when you take it off this is probably not the issue.

Hope that answers it, I am by no means an expert in this field just have had to clean my share of carbs .
