Red face What air fuel reading should I be getting from the A/F gauge??

I am almost finished hooking up the gauge, just curious what I should be seeing on it... For the life of me i can't remember what is the happy spot


Thanks John

Closed loop it should fluctuate between like low 14's to low 15's. 14.7 is stoich. Mid 11's to 11.8 with the happy pedal down.

Hmmm ok, it is cruising in the happy zone, 1dles seems to be 16. I notice under part throttle it jumps down to low 11's - into the 10's but comes out of it back up to 12-13. That isn't good to be jumping down that low. Havn't beat on it bad, due to it doing that at part throttle, but seems with it coming back up in to 12's it should be good in the upper rpms, but don't know.

16 is lean. 10 is rich.
