Setting timing without pointer

NOW before you put the tape on, measure around the wheel, figure the measurement around to equal 40 degrees, and mark that off, so that you know where TDC is and you know where 40 degrees advanced is............



and make sure the 40 mark on the tape lines up with your 40 mark on the wheel, and NOW you can...........



The tape comes for different size balancers. If you don't check it, how do you know it's correct? And of course, make sure you apply it in the correct direction.


That means I have to use that fancy math!
