Sometimes you just have to bite the bullet and back her out. Could be that it was cross threaded on installation, or boogered a thread which is galling up digging a trench as you try and back it out. To fix it, got to get it out. Can always try tightening it back up then try pulling it again. might be enough to clear anything thats hampering it. Rare though...
Hold your tongue just near the corner of your mouth, left side squint with your left eye and hum while pulling it. Sometimes this works and all you will have to do is chase threads. Flipside of that if tongue is out of position...you maybe dealing with an insert repair until a proper fix can be done with head off.
Get in there and give it hell man!
