Yep I was unsure if I went past the time mark so I loosened the tensioner & rotated in the direction to start the tensioning process again, being a little softer when the marks aligned.
I get a little confused with all of the naming conventions on here. By " pulley on the end that you have just been working" Im guessing you mean the cam "sprocket"? I refer to anything with teeth as a sprocket. Or is there another "pulley" somewhere that I need to loosen?
