My deep 18mm socket WILL NOT fit down into the recess where the #3 spark plug sits...and yes, I did remove the little housing where the tach plugs into the head above. The only other option seems to be to remove the head? To change a spark plug? I know this can not be correct. Do I need a special socket for this? Mine fits just fine onto the other 3 plugs.
Thanks in advance,
Jeremy
