Flathead Timing

New to the site, but I finally got here!
I'm a Naihead and early Hemi guy just entering the Flathead World. I've got an 8BA '49 Mercury Flatty I just upgraded my Mallory Dual Points Dizzy with the Pertronix Ignition Module.
I know how to find TDC and from what I hear Flatheads don't care for too much timing at idle- 4 deg.
So, my question(s) are...
Where are the timing marks on the original Crank Pulley?
How do you set the initial and full advanced timing?
On average, how much timing does an 8BA like at idle and full advance?
Much Appreciated.
"Big" ED.

Sorry, I'm not a flathead guy either.

 

Thanks, Phil.
For both the welcome and the link.
I have a wealth of useless and currently unused knowledge if you ever get in a bind!
