I do not disagree with you. I have always been taught that you get the timing in the ballpark and then work on air fuel ratio. I think maybe it's because it's more stable or simple for lack of a better term, as compared to the carb that has several circuits and is somewhat primitive and dependent on various factors such as driving conditions and such, not to mention octane or ethanhol mixed fuels. I think after the basics are set going back and forth between the two is key to fine tuning. It's doing the hard way what car computers do in Mila seconds. I wonder why we spend so much time trying to make these primitive carbs act like something they can never be. It must be the challenge, you think.
