Just my 2 cents to start with, all carb tuning and adjustments need to be done with the engine at operating temp. Trying to judge fueling on a cool motor is a waste of time.
I would suggest you go back and sort out the pilot jet first. Get the idle fueling dialed in and then the pilot jet fueling (up to but not beyond 1/4 throttle" figured out.
Once you have the idle mixture and pilot jet sorted, leave the needle where it is for now and then sort out the main jet. Why? It's the second easiest jet to figure out since it only majorly affects the fueling beyond 3/4 to wide open, especially 7/8 to wide open.
It's a good idea to have a few clean, new plugs handy for doing this type of work. Not because they go bad, but because starting with a clean plug when doing a plug chop to check fueling helps ensure you eliminate many of the other variables. A Proper plug chop also means you hold it in that throttle position for several seconds. Some people say minutes, but I have found that, at least for wide open tuning, is a bit unreasonable. 10-20 seconds is often enough to get a good idea if you cut the ignition and throttle properly. Obviously the longer you can hold it the better.
Once you have the pilot and main sorted now you can finish with tweaking the part throttle tune with the needle position.
Whatever you do, be very mindful of how tight you tighten the plug on a hot engine. Stick to finger tight plus 1/8th of a turn so you don't strip the threads in the aluminum.
