Great video. Very worthwhile to see it in action. I stumbled across some of the same info in the CIS Primer. Might be helpful to others to see it explained in print:
911 CIS Primer - Testing: Mixtures
It seems like in the video he’s going back and forth adjusting the mixture and the idle. Is that correct? Seems like you’d adjust the mixture and once it seemed correct you’d adjust the idle.
Also, my mechanic mentioned he needed to check/adjust the mixture both from a cold and warm start. But the instructions I’ve read discuss setting the mixture from a warm start only. Do I simply set it warm and then check/adjust the following day from a cold start?
