OK I went to change my spark plugs today and whoever last worked on this thing stripped the set screw for the coil on cylinder #6. I have no clue how to get this out of there know. my only guess is to drill it out with a tap or something but of course I have never done that before so I have really no clue how I'm going to get this thing out of there, those tiny little set screws have to be the worst idea Please help
