Sorry I didnt mean to make things worse, it's just the way I do it. Yes you are on #6, as per the gears, but I dont see rotor?
I'll confuse things more...my brain ain't right, but a crank turns 2 revolutions per complete firing of all 8 cylinders. 2 revolutions is 720*. Well 720* divided by 8 cyl gives us 90*. So every 90*(or 1/4turn) of crankshaft gives you the next cylinder in the firing order(18436572) firing.
