So I got this here 50hp 2 stroke yammy...I have both the owners manual and the service manual. But neither tells you how to 'adjust' the carbs like the mercury manual does. The service manual tells you how to remove the carbs and re-install them, and shows you an exploded parts diagram...I found the chart with the float height and etc...but for the life of me I can't find where it says my idle adjustment screw and my carb needles should be adjusted at...IE- '1.5 turns out from lightly seated'. The merc manual for my old outboard says this in plain english, yamaha, not so much. I have a carb kit coming this week for all three carbs as well as a new fuel pump, fuel filter, and fuel enrichment gaskets/diaphragm...but when I put it back together, it doesn't tell me how to adjust that silver carb needle inside of each carb? or the pilot screw on the side of the carb under the cap?
