Will the optimium A/F vary with the application? I have a KB S/C and for some reason that I'm still figuring out, the A/F is at 13.5 which most people are saying is lean. However, based upon the A/F range posted above, my mixture is rich. Is this about right?

Thanks for the info.

I was always confused about this .

On the technical side (13.1) means 13 part of something for 1 part of something...I don't really need to know that but I'm curious.

One more: Why the A/F curve is not as smooth as the H/P curve.
