Am I reading this wrong or are you saying to use the a/f or pilot screws to adjust sync? Sync is a mechanical adjustment to make sure all carbs pull the same air by adjusting the position of the butterflies. Has nothing to do with a/f mixture or slow jets which should be adjusted using a O2 sniffer or plug check and wag it?
That's what it looks like, but where does it screw in?
Anyone have a pic of where it goes?
