whats the best way to adjust the carbs on a 1996 evin 200 hp,,,I have the manual and it talks about one carb but do i make the 1/8th turn adjustments on that one mixture screw or to all 6 of them and then wait to see is the engine changes. is there a better way like a guage to get them even or by ear?? I know the manual talks abouit 5 turns out I have done that and did a liitle adjustment to where the engine seems to be ok but to fine tune it is there another way? thanks.
