That is a very low AFR idle. An idle adjust won't affect your cruise AFR much (slightly). Does the engine sound happier with an idle AFR a bit higher (12 ish?). They are all a bit different and as the engine ages they tend to like more fuel. But mine is happy around 12. 13 gets a bit rough, and 11 gets sluggish (labouring).
