<VV> Carter YH choke question

[Markpowhatan at aol.com]

I have a 63 Spyder with rough cold running issues.  The carb was  rebuilt 
by someone else, and upon inspection i noticed that the choke has spring  
pressure holding it shut, even when the round black cover and coil spring are  
removed.  My coil spring in the cover was installed to push the choke lever  
up with the flat side on the back of the "hook" in the end of the choke  
coil.  Isn't the hook there to push the choke open when sensing heat, or is  
it supposed to be the other way so that the hooked end keeps the choke "from" 
 opening until heat builds.  After warm up, my choke stays open with spring 
 tension even after removing the round cover with the spring in it.    Any 
ideas would be appreciated.     Mark  Francis    63 spyder   powhatan  Va.
