Glad to hear your carb is up and running again. It sounds like it really needed a rebuild.
I don't know why you would want to remove the choke plate. Obviously, if you remove it you won't have a choke which is not so good. I guess it would work if you want to sit in a cold Jeep, nursing the throttle, waiting ifor it to warm up enough so it will idle without your help.
If you remove the plate but leave the rest of the choke you wil still have the fast idle cam. So, it might cold idle by itself. But it certainly won't drive very well when its cold. I don't get it.
