1972 Johnson 40HP 40EL72E Fuel Specs

[thalter3]

I have finally got my boat motor running at idle. I am curious if anyone knows what the specs are for the fuel screw on the front and how to properly set it. its running decent but is skipping like its misfiring but it definitely is not. I found this but i am not sure if it correct. https://blog.marineengine.com/2018/09/06/johnson-evinrude-carburetor-adjustment-by-joe-reeves/

That picture is not for yours.----Open the low speed mixture screw 1/8th turn at a time and test.----Make sure throttle plate is closed at idle.----Make sure throttle plate does not open too soon.
