I manage to get it clean! First I sank it into a diesel for a 24h... did not help much... Then few hours in detergent... Not much help... Then I gave it a ultrasonic bath, the result was better, but there were still some green stuff left... Then I bought some carburetor cleaner and spray that and the green stuff melt away... Last cleaning with brake cleaner... Now the carb is back in one peace... after a week, I we'll see if it works, or is there something else broken...
