Throttle/carbs issues

[vladgluhovhere]

You're saying you still have the problem with the carbs out and no tension on the cable? I'd try putting the old cable back in and see does the problem go away. If it does then the new cable is at fault. If it doesn't there must be something wrong in the carbs or you have two faulty cables which seems unlikely. Did you have this problem before you did your work? If not then you know the old cable is good so if there's still a problem when you put the old cable in there must be something wrong in the carbs

Starter with the old cables, I bought new ones as "last resort" option, which wasn't...
Carbs were out for literature half an hour and I've only done float chamber and jets at the time. When this problem appeared, I rebuilt the carbs completely.
