Automatic Idle Adjustment One Person HOW?

Very safe, VERY easy. SET IT IN NEUTRAL. Set the idle up, set the mixture, be CERTAIN it is properly set AKA fully warm, mixture correct and TIMING correct.

THEN GET INTO THE DRIVER'S SEAT and put it into drive, and see where it lands. If it is too high or too low, just turn the screw a little bit

First time I did this was about 1966

This sounds like the safest to me ,,,,,he’s known this since 66,,,,almost 60 years .

Lol ,,,,,but the funny thing is that no one knows how to adjust a parking brake ?
If the park brake won’t hold a car in gear at idle,,,,its useless .
