Travis,
If you have the line running from the cover plate into the fuselage, then the carb plate will not do much, if any good, it is basically doing the exact same thing which is to stop direct airflow over the hole in the plate. Now that we have a bit more info on the needle and stack locations, I would try leaning it a bit, then if that does not settle it down, remove the stack.
I will lean out the low end a little on the ground until it runs smooth at all throttle settings. If it gurgels at low throttle in the air after that, then sould I lean the low end just a tad more, or go ahead and remove the stack?
Thanks again for all the help everyone,
Travis
