I can't find my timing mark when I have my light hooked up to number 1 spark plug. I have even advanced and ******** as far as you can go both ways in attempt to find it to no avail. Out of curiosity I decided to hook my light up to the other plugs. when I'm hooked up to the number 3 spark plug there it is. I'm not sure what is going on with my truck right now. Anyone got an explanation? I thought you hooked up to number one to adjust the timing.
