Some say to make my idle adjustment 750-800 rpm in the water in gear tied up to the dock. Shouldn't it be made in gear moving across the water? due to the difference in prop pressure being tied to the dock and not?This carb work sucks 75 hp 1996 Force single carb. The guy i dought the boat from thought you made the idle adjustment on the lingage rod going to the cam instead of the screw at the top of the tower.So i have had to start from scratch.
