Absolutely not. The last time my cam saw daylight was in May 1974, in
a little place called Abingdon. But the motor loves ignition advance anyway.

I don't know.
I can ramble on about things like carburetion and ignition, sometimes
even drawing on factual information, but I have exactly ZERO clues about
ignition advance and its relationship to performance.
