Does anyone know the proceedure for adjusting the idle mixture screw on a 18HP Tohatsu? Should I adjust the base idle speed in gear and at what rpm? Thanks in advance.....Savage

it should alway be done, in gear, in the water at idle.(not on the muffs, actually IN THE WATER) i dont know for sure what your idle speed should be though, im thinking about maybe 700 rpms sounds good

Set the screw at 1 3/4 and then adjust from there.
