i'm in the process of cleaning out and rebuilding the 4 carbs on a 99 125 merc. i have bought all the gaskets, new floats and needles, and was wondering, do the new quicksilver floats usually come already adjusted from the factory, or do i have to mess with bending the tabs and setting them myself. and if so, what should the setting be for those carburators. <br /><br />thanks
