I drilled out all the small brass bushings, and tried to dig out som foregin matter I observed.
The reason for taking them out, was when i compared the flow through the pilot passages(I blew by mouth xD) i found great resistance in the carburetor.

I found some plastic/fibers in the passage, and they were quite difficult to dig out. Maybe som eearly tinkere tried to clean the carburator beforer me

I did a VERY ruff adjustment of the carburetor, and assembled everything again, this time with no smoke from the exhaust and two sparkplugs that did not build up crazy carbon deposits within a few minutes.

For now I believe the bike kan be tuned correctly, but i will let you know and post a video when that time comes

Thank you so much for all your inputs so far
