***RESOLVED*** replaced dead battery, now engine doesn't turn over.

You have points I see. If you don't have a timing light you can check timing "static." I would not move the timing arbitrarily, because if the cam has slipped, this will throw you off direction

If you have a wrench (I forget, 1 3/16--1 1/4) for the front crank bolt, you can bring the engine up to TDC, put your test lamp on Coil NEG with the key turned to run, or just look for a spark at the points

Slowly wrench the engine until the points open, wherever "that is" on the balancer is where your timing is.

Of course if you have a timing light, you can check spark "on the starter" This is yet another way to see if you are getting any spark at the plugs.
