Idle mixture adjustment on 90HP yam(2st) 2006
My new engine works otherwise perfect, starts easy, very smooth under load but seams to have a fuel related issue on idle. Poor idle and and might shut down unless increasing the rpm over normal idle. No difference warm or cold. Fuel filter ok, sparks ok, pretty sure its carb related. Burned 60 l gas today at good load but still the idle was not optimal.
Have located the idle mixture adjustments screws. Any hints what is the basic setting(how many turns from closed) and any tricks how to get all 3 carbs tuned.
Not excluded to take engine to service, but rather try first the DIY way. Thanks
fun on a boat is inversely proportional to size...sort of anyway
