Re: 77 Johnson 6 Leaning Procedure
See the item "HOW DO I ADJUST MY CARBS?" in TD's "Top Secret File"
Adjust the needle as described and refit the knob in the mid point of its range.
Once set you should not normally have to alter it but if necessary you can tweak the idle mixture adjustment by turning the knob clockwise to weaken the mixture or anticlockwise to enrich it.
