Two thoughts: (1) new coil connection, and (2) the affect of closer point setting.

When you replaced the coil did you connect the positive (+) terminal to the distributor? An incorrectly connected coil can cause performance problems. The Packard uses a positive grounded electrical system. Your battery should be positive ground unless someone has changed it to negative ground.

The closer point setting will allow a bit more dwell and more time for the coil to re-energize. You may have a bad coil, even if it is new.

Good luck. JWL
