Went to do a compression test on my car for a potential buyer, first spark plug hole the damn thing got stuck and it took two hours to get it out without damaging the car!
So then of course because I was doing this in the driveway, I had to put the whole thing back together in the dark by feel. But took it for a test drive and all is well so thankful for that
At least I now know that I can literally change sparkplugs with my eyes closed!
Protip: if you\'re buying a compression tester that does both sized spark plugs, loctite the s*** out of it before using.
