Need help indexing timing chain sprockets.

[Nashty]

I have a rollmaster timing chain set on the motor when I got it. The crank sprocket has multiple keyways and (2) dots on the thing. One is in line with a tooth, the other is at the base of the arc between the teeth. The mark on the cam sprocket is visible.

I didn't mark the sprockets when I removed the assembly (RATS !!) so now I need help. Can you help me identify the correct marks to set this up with?

I bet you have it solved by now.

But just in case not. 2 dots on crank sprocket---1 dot will line up with the keyway, this where the key will go to be straight up. That will make the other dot line up with the cam gear. Lay them down on a bench assembled it it will be clear. Hope this helps.
