My thinking is you may have the wrong needle and seat. Although they look good to you and fit the hole, might be from another bike.

hey guys. couple months later but im back on this side of the planet. i took out the carbs again and left them a day in pine sol, minus the rubber parts of course. seemed to clean it up pretty good. i adjusted them once again perfectly to the 22mm floater height and mixed the parts up instead of using the same parts in the same carb as before. lets see whats the result after im getting gas and fire her up. either way: just want to say hi to everybody!

Hey guys. Hope everybody is fine. I havent touched the bike in a long time now but finally got the motivation to continue. I had similar issues with my dune buggy in the Philippines and it turned out to be the fuel cock. They are both vacuum cocks. I just want to throw in a quick question. When I suck at the vacuum hose that is connected to the tank, gas should flow freely right?

No where is the vacuum hose connected to "the tank"
The vacuum hose is connected on one end to the petcock, the other end connected to the vacuum port on the #1 carb intake manifold.
Leaving the hose connected to the petcock, disconnect the end of the hose that connects to the intake manifold and *lightly*suck, you should hear a click, the petcock should open and gas should flow.
Stop sucking and the petcock should close.....no gas, not even a dribble, should flow from the petcock.

Exactly. I need to fill in some more gas in the tank later to be sure its working. I took the carbs apart again right now cause I havent used it in a few months but they are still clean as new. When I suck I can hear that something is closing inside the petcock but now gas or very little is flowing. Thats why I want to fill in some more to be sure its not too empty right now to freely flow. Then I will check again the fuel level of the carbs with the hose while running. Thank you buddy

Filled in some gas, works perfectly. Back to test the carbs I guess.

  Be sure that the two vent hoses connected to the white plastic T fittings are clear of obstruction. This is where the float bowls get atmospheric pressure. When you have the carbs off, be sure the holes in the roof of the float chambers are open to the fittings that the hoses connect to. You said something about fuel coming out(or not coming out) with the carbs on the bench. The fuel will surely come out those two hoses when the carbs are turned over.
     Good luck 303,,
