Carburettor/Choke

Hello guys, I’m new here and need urgent help. 94ger Evo engine with original carburetor. The motorcycle was standing for quite a while. I cleaned the carburetor 2 x. The choke system doesn’t work. She probably doesn’t get any gasoline with drawn choke. Don’t jump at all. Just start with accelerator pump. So always turn around the gas until it runs. Membrane sits, nozzles are clean. Does anyone have a tip for me? Thank you very much.
