Lets us be sure that the trailing plugs fire at the same time or later than the leading plugs. Never before the leading plugs. Very bad Mojo.
It is mental gymnastics for me every time I look at this. This means that if I use 20*BTDC as my firing point for the leading, the trailing should fire at a number less than 20. Another way to look at it is the mark on the timing wheel for the leading should pass the indicator BEFORE the mark for the trailing.
I'm positive I've got that right now. I'm also positive that keeping this stuff straight give me a headache.
