question on timing

ok, i dont have a timing problem, but i still want to know how/why it works like this.
at 750 rpm, L1 should fire at yellow (first) mark, T1 should fire at red (second) mark, T2 fires on opposite side of pulley as T1.
where i get confused is that...L2 fires at yellow mark also?????????
could someone (scientifically) explain this to me, just to satisfy my own curiosity.

There is only ONE Lead coil. It fires both Lead plugs at the same time. Read this: http://www.teamfc3s.org/info/articles/idle.html

um...that was informative, but it never even mentioned coils.
anyway, turbonut pmed me a very detailed explaination and were talking about quite a few things that may help newer people (like myself) understand and be able to diagnose coil and idle timing problems a little easier by means of understanding them better. thanks though, i did learn something from that to.

just time it so that you can turn the idle down, it dosnt smell like gas, there isnt any slight stutters at idle, and starts ok. thats all i did and it works fine. someone tried to explain all this complicated timing bs nd i made it worse, i did it my way and it took me 5 min.
