[AT] Seeking Choke Return Spring Ferguson TO-20

[SZakaluk at aol.com]

I'm looking for a source, or comments.  While moving snow today, I  lost 
the choke spring from my 1951 Harry Ferguson TO-20.  No chance of  finding the 
old one, at least until the snow melts.
 
Probably any spring would work, but I'm not sure how the original hooks  
up.  My manuals aren't any help in identifying this part.
 
Thanks in advance for any thoughts.
