I have a 1949 Lincoln Cosmopolitan Town Sedan. The engine bay was a mess before I took everything out and restored it. I did not notice how the mangled spring to the carb was connected. I have a new one now, and am trying to remember how it was attached. I assumed to the firewall, so the accelerator can return to its idle position when the carb does. With all my 1949 Lincoln shop manuals for this, you would think they might have had a picture! The only way I can see it attaching is through a small hole in the firewall. Is that correct?
