RE: [Honda-C70] Re: removing a cylinder head stud

If the head had 3 chrome acorn nuts on studs & 1 plain nut & copper sealing washer on the other stud . The one with the plain nut & copper washer would be the oil passage. Mine is on lower left [if I didn`t switch them when I had the head off ] . Have never had the cylinder off so I don`t know how the studs mount . Good Luck ! Baby Huey

The cylinder head is off and I can turn the stud anticlockwise but it doesn't seem to be screwing out and I can't pull it out although it appears loose and can be rotated by finger pressure. Am I missing something here as I had assumed the stud threaded into the crank case? None of the diagrams I've looked at show exactly how the stud fixs in the crankcase. My questions are why will the stud not screw or pull out?. How is the stud held in crankcase? Do I need to take off the cylinder barrel to remove the stud?
