A Jesel makes it easy. What I do with a Jesel is install the cam with the line at zero and then just check it. Most of the time it will be correct. If it isn't correct you just loosen up the upper pulley and move it the amount needed. Usually only takes a few minutes. You do need a degree wheel, a pointer and a dial indicator with stand. If you don't have any tools then you'll need to have a local car buddy swing by and help.
