Mr. Russel, Q. regarding flamefront speed.

[KryptoSol]

I always forget, is flamefront speed fastest around 12.5, which would require less ignition advance when compared to anything richer or leaner than 12.5??

Sorry... kind of a newb question. I always find myself sitting here thinking about fuel/spark and end up thinking myself into confusion.

sweet, thanks for the quick reply.

Its funny b/c not till just recently i would just focus mostly on ignition (as long as a/f was in check), and not really understanding how the two interact. But now i know its a balancing act of the two.
