Okay I figured by looking at the pickups inside the stator cover that it would have to fire every rotation, much like a lawn mower or other small engine. Unless somehow the IC or whatever it is called somehow knows when the compression stroke is and only tells the coils to fire then. Can I check the timing with a light without the engine running. The only thing I could find in the manual it says the engine has to be running at a certain rpm and the marks will line up. If I check it with a light with just cranking should the marks still line up?
