What is the relationship between Air/Fuel ratio and rich or lean. For example: My air /fuel ratio at idle (900 RPM) reads 13 to 14, Yet my car bleeds fuel into my exhaust and backfires in pipes? I understand 14 AFR is a good number? AT the carb shop they said to go from a 50 to a 40 in the accelirator pump discharge. Does this make sense to minimise fuel going to exhaust. I am trying to set carbs for stop light to stoplight performance. Since most of my driving is under 70MPH I do not care about going 100 or more.
