I dont have it backwards. On that model carb the spring on the pulloff helps close the choke untill the vacuum pulls it partway open like you said. The choke therm coil has to overcome the spring tension on the pulloff or the choke will reapply on full throttle when the vacuum is low. I have had to cut some coils out of the spring on some to get the right adjustment. I have worked on hundreds of them.
