merc 9.9 model 1010201L 1991 s/n 0D002808<br />I had the carb apart once to repair stuck needle valve, after the repair the manual idle which is a dual choke and idle setting knob, the fast idle would not work when the knob was turned all the way to the right. I have the factory service manual but the procedure they describe will not work. It seems like not enough pressure is applied to set the idle up.
