Something is binding. The spring on the pulloff should snap it shut as soon as you open the throttle. It may be like Rusty says. The choke plates might be be rubbing. If not then the linkage is binding. You need a good choke thermostatic coil on that model. It has to get hot enough to overcome the sprint on the pulloff.
