1983 25hp Evinrude Carb "knob"

There is a knob above the carb and wanting to know what it does. Does it run the engine leaner if you wanted? How do I know its in the correct setting? Thanks

that is the lean/rich knob
adjust it so it idles normally, then make small adjustments leaner/tightened until the idle changes sound. when that happens, use that as the center point, so you can go up or down from there.

If you are unsure of the current position and engine does not idle properly, gently seat it (not farmer tight) then back out 1.5 turns. That should get you running then adjust from there.

It ain’t no mystery…this beer’s history!

Thanks!
