150 yamaha idle adjustment

[phatdaddy]

i have a 2003 150 and the idle adj is on the middle carb. with the cowling removed stand over the air shroud and look straight down on the starboard side at the middle carb. should be a phillips screw looking back at you. if you work the butterfly's with your fingers, you will see the one . it might be easier with the air shroud off , but its a pia with 12 screws holding it on.
