You could be 100% correct. Its very possible that all the carbs I've worked on have been so old that the notch has worn off - I know i've never noticed it. It has been almost two years since I've been inside the choke housing too.

So it sounds as though this notch is still in place on this carb. If thats the case then the choke plate linkage is probably not hooked up correctly, which is indeed what Stock87 originally said. Look at my previous post to try and understand how to get the linkage right.
