Cool!  This can be very confusing because it is tough to determine if the seal is in place by looking inside the threaded hole for the low speed needle.  Like I say, this little rubber/plastic cup is what takes the place of the older style packing and nut.   So, if you have an engine that won’t idle consistently, or you just can’t seem to make it rich enough to idle, good idea to make sure this pesky seal is in place.
