Question edited for full 'year make model (what it is).
Question moved from motorcycles to make model category.
Please don't type in all CAPS, it is considered SHOUTING and is harder to read.
'clips' and 'turns' it took me a while to realise you were talking about the carburetor and you were playing with the mixture screw and needle position! 4 turns out is a lot different to the factory setting which is 1 1/2 turns out.
If it is overheating it is running too lean. As you changed the stator, also consider the ignition timing. Popping can also be caused by the ignition failing under load, coil, lead and spark plug.
Carburetor and tuning.
