So I gave up on my 1976 Johnson 70hp. I purchased a 1979 Evinrude 75hp. I want to put my Boyseen carbon reeds in the new outboard. ON the 70hp I went up 2 sizes on the slow jet per instructions.
The 75hp has 3 jets High/Slow/Idle. Does anyone know should I richen the slow jet like before or richen the idle jets (angled top of carb) and if so are those idle orifices metering fuel or air?
