Moin folks, Got the ignition up and running and cleaning the Mikuni carb as the Trab still isn't starting. Looks like I am missing the above part, maybe from a previous cleaning or adjusting. It seems like it would be important and necessary. Can any Mikuni owners let me know if this part should be there? The car used to run, and I find it hard to believe that I lost this or that it came loose.. I appreciate the help!
