Don't even try to set the ignition timing until after you've run the engine for the first 20 minutes at a high idle and changed the oil and coolant.

For the initial warmup, just set the distributor in the middle of the adjustment slot - it should be fine. You can move it around in the slot to find a better spot if it stumbles.

You don't ever want to try to set the ignition advance on a cold engine. When you do set it, be sure to ground the wire at the firewall and set it at 5? BTDC. Once the base timing is set, remove the ground wire and the lead should change to ~ 15? BTDC at idle.
