Um ok I haven't even messed with my cas timing I figured I didn't need to adjust it cause I took off the whole arm and not the actual cas from the mount. Should i go purchase a timing light and set my car timing via cas? If so I have never used a timing light I know how they work but loosen the screws slightly on the cas and turn counter clockwise for retard right? So 15 degrees Btdc is where I wanna be? What's that look like on a timing light?
