Sorry, I have to ask... Righty tighty, lefty loosey?![]()
Either a 1/2" socket with a fairly long ratchet or a long box wrench should work. Hold the wrench/ratchet firmly with one hand and give the end of the wrench a good rap with the palm of the other hand. Most stubborn things respond to a good firm shock.
If that doesn't work, then some heat at the base of the plug could be helpful or let them soak in some penetrating oil overnight. The heat would help then also.
I was told .035 for a standard compression engine
Sounds like Hulk Hogan tightened those bad boys last. Evidently have not been out in a very long time.
