Lean mixture

[MACADO1]

Mikel. I posted my last question about knock, late Friday, I think it got lost in the shuffle.

At what point(A/F ratio) would the car pull timing, and about how much? I would think that if my A/F ratio was as high as he says it is,( 13.7 to 1 @ 5000+ RPM.) I would be getting some long term knock, or a lot of short term knock. More than 2 to 2.5 deg. I'm getting.

there is no set point for this to occur, but if it goes lean, it will likely knock.
