I had that cable in my 41 Sedan. Never found out what it is usefull for as it snapps back when you relase it.
I also first thought, it is for easyer starting with the footstarter, but found out that the footstarter bow pushes on the accelerator linkage anyways and has a bolt to fine-tune that.
Got me one of those "twist&lock" cables at the local truck shop and use that as a "cruise control" on the german Autobahn as Jimmie said.
