Going back to carb seems it must be something there, could the fuel mixture screw go bad and not seal anymore.....

The o-ring can dry out and crack. But with mine a 10 degree temp change and humidity change will warrent a little fiddling with the fuel screw to get it working properly again.

fried CDI = no worky
when they go bad, they normally stop working altogether

have you had the carb apart and cleaned it all
clogged pilot jet normally results in idling issues
not worth cleaning, just get a new one

Normally, but not always.

Stick your CDI in the freezer for 3-4 hours. Remove it and immediately plug it in to the bike and see if it runs better. Thermal intermittants (usually bad solder joints ) are not uncommon on CDIs.
