31 Spark Retard

Posted by Greenfield On 2020/6/22 10:48:36

The question du jour is how much do I retard the spark at startup for a 31 Packard? The owner's manual doesn't mention retarding the spark at startup, only that it should be pulled out 1/4" if going 5 mph or so. My instinct tells me though I should retard it somewhat then go to full advance as the engine rumbles to life. Any thoughts?
