At 9:50 you can see when I put it in gear, the reading goes lean and stays put. I’m not sure what causes that. Could be the initial “pushed” gas was a bit richer than normal.
At any rate, it’s never gone overly rich, just enough the meter shows it. Anytime under load it stays right on target, occasionally it will go a tad rich when you romp the throttle. I’ll have to make (yet another) video showing the AFR as I drive around town.
Nope, that’s the thing… there’s no initial adjustment because the full range of travel is under the control of the diapghram. No matter where you set it, it will rebalance itself.
