Like the title says: I somehow have managed to strip out the nut head on the top of my cable holder for carb slide. I thought it was a little tight while trying to loosen for adj needle clip. I've tried needle nose pliars and vice grips but that dude it stuck. I know it isn't cross thread but don't know how it's seized. I've sprayed some wd40 in there to soak but really not sure how to get it out. Any helpful suggestions? Sry for putting this in general forum but I wasn't sure.... Thanks in advance!
