Choke handle was completely loose.
Inspection after removing seat and fuel tank revealed this defect. Tack welds said "thank you" after 37 years of service.
As new tack welds or other welding was out of the question, I turned to glue. The area to be glued is quite big, so I would give it a go. Casco Strong Epoxy Metal was selected for the task.
Initial sanding and cleaning...
Glued and mounted part.
Hopefully the epoxy will do the trick.
